Which one of the following is NOT true? Enzymes are used up in chemical reactions. An enzyme's function depends on its three-dimensional shape. Enzymes emerge unchanged from the reactions they catalyze. Enzymes are very specific for certain substrates. An enzyme binds to its substrate at the enzyme's active site.

Answers

Answer:

Enzymes are used up in chemical reactions.

Explanation:

Enzymes are biological catalysts that speed up or accelerate the rate of chemical reactions within a biological system. Enzymes regulate the rate of chemical reactions without being destroyed in the chemical reaction nor altered in the biological process. Specific molecules called substrate, bind to the active site of enzymes to produce molecules referred to as products. Enzymes are vital to life as they participate in so many biological process in body such as in digestion, DNA synthesis. The function of an enzyme is dependent on the three-dimensional structure of the enzyme.

An example of an enzyme is hexokinase, that converts glucose to glucose-6-phosphate.

Final answer:

What is the role of the lymphatic system in the innate immune defense

Answers

Answer:

The lymphatic system carries out the body's immune responses by producing and distributing cells, such as lymphocytes and macrophages, that combat disease. Lymph vessels, or lymphatics, drain fluid from all parts of the body and return it to the heart.

Explanation:

The lymphatic system is vital for innate immune defense by producing, maturing, and circulating lymphocytes, and filtering pathogens from lymph fluid.

The Role of the Lymphatic System in Innate Immune Defense

The lymphatic system plays a crucial role in the body's innate immune defense. It consists of a network of vessels, ducts, and organs that manage the fluid levels in body tissues and filter out pathogens. One of the primary functions of the lymphatic system is the production, maturation, and circulation of lymphocytes, a type of white blood cell that is vital for immune responses.There are several key features of the lymphatic system related to the immune response:Production of Lymphocytes: Lymphocytes are produced and matured primarily in the bone marrow and thymus.Filtration: Lymph nodes filter pathogens from the lymph fluid before it is returned to the bloodstream, providing an essential checkpoint for immune monitoring.Secondary Lymphoid Organs: These include structures such as the lymph nodes and spleen, where mature lymphocytes congregate to detect and respond to foreign invaders.Transport of Immune Cells: The lymphatic system transports immune cells throughout the body to intercept pathogens and mobilize an appropriate immune response.Although lymphocytes are primarily associated with the adaptive immune system (specific defense), the lymphatic system also supports the innate immune response by filtering pathogens and by aiding in the initial activation of immune cells. This helps ensure a rapid response to infections, preventing pathogens from spreading throughout the body.Overall, the lymphatic system is indispensable for both innate and adaptive immunity, providing both immediate and long-lasting defense mechanisms in the body.

The evolution and later reliance on our ______ system has been suggested as the reason why humans use pheromones less than other mammals as sexual cues.

Answers

Answer: Reproductive system

Explanation: the reproductive system in humans which is a complex system that consists of sex organs that work together for the purpose of reproduction. This system has taken over the use of pheromomes in human and some other mammals as sexual cues.

Final answer:

Humans use pheromones less than other mammals as sexual cues due to the evolution and reliance on our olfactory system. Though humans still respond to certain pheromones the prominence of our visual and auditory systems and the complexity of our behaviors have reduced our reliance on them. The role of pheromones in human interaction is a subject of ongoing research.

Explanation:

The human sensory system referred to in the question is the olfactory system. Pheromones are a type of secreted chemical signal primarily used by many animal species to influence behavior, including attracting the opposite se issuing alarms, or marking food trails. In humans, however, the prominence of other sensory systems, particularly the visual and auditory systems, and the complexity of our behaviors reduce our reliance on pheromones.

Although humans are still thought to respond to certain pheromones, such as axillary steroids, our response is considered less significant compared to many other mammals. This is essentially due to our sophisticated olfactory system's evolution and our greater dependency on it. The less obvious role of pheromones in human-to-human communication continues to be a subject of scientific research.

In context, our evolution and increasing reliance on the olfactory system, which processes complex scents and aromas, has likely influenced humans to use pheromones less as sexual cues compared to other mammals. This shift towards olfaction and away from pheromone-based communication is a fascinating aspect of both biological and sociological studies of human interaction.

(a) Explain why this is the case:


Answers

Answer: It is necessary for the immune system to clearly distinguish foreign cells and proteins from those made by the body so that the immune system will be able to fight foreign cells and proteins and eliminate them from the body.

Explanation: The ability of the immune system to clearly distinguish foreign cells and proteins from those made by the body helps the body to identify pathogens that invade the body and trigger appropriate immune response to eliminate the foreign cells and proteins.

When the immune system of the body fails to distinguish foreign cells and proteins from those made by the body, the body launches an attack against its cells, that is the immune system triggers an autoimmune response in which attacks are launched against the cells of the body and destroy them. This condition in which the immune system recognizes the cells of the body as non-self and launches an attack against them is known as autoimmunity. Autoimmunity is the major cause of most degenerative diseases such as type I diabetes mellitus.

Answer:Respiration and photosynthesis

Explanation:

The proton gradient is formed by the electron transport chain and this is across the inner mitochondria membrane that enables ATP synthesis through chemiosmosis.

Oxygen is needed in the cell for oxidative phosphorylation and it is of 2 component this include the electron transport chain and chemiosmiosis.

Electron transport chain- Electron are transport from one molecule to another.

Chemiosmosis- The energy is stored and then used to make ATP.

Final answer:

Proton gradients across membranes are generated during chemiosmosis, a process that is part of energy production in cells. This process involves the movement of hydrogen ions across a mitochondrial membrane to create concentration and electrical gradients known as the proton motive force, critical for ATP production.

Explanation:

The generation of proton gradients across membranes primarily occurs during a process known as chemiosmosis. This process is involved in the production of adenosine triphosphate (ATP), an energy-carrying molecule, in cellular metabolism. In chemiosmosis, free energy is extracted from a series of redox reactions and used to pump hydrogen ions, or protons, across a mitochondrial membrane.

The movement of the hydrogen ions from the matrix into the intermembrane space creates an uneven distribution across the membrane, thus establishing concentration and electrical gradients. This is the result of the hydrogen ions' positive charge and their aggregation on one side of the membrane. This electrochemical gradient, often referred to as the proton motive force (PMF), is integral for the creation of ATP.

So, in essence, the generation of proton gradients across membranes is a key part of energy production and transfer within cells, particularly during the chemiosmosis process within mitochondria.

The sliding filament model of contraction involves ________.

Answers

Answer:

The sliding filament model of contraction involves actin and myosin sliding past each other and partially overlapping

Explanation:

Sliding filament model states that during muscle contraction the myofilaments myosin and actin slide towards each other and overlap. This shortens the sarcomere and the entire muscle/ Muscle cells are shocked by nerve impulses from motor neurons.

The force behind the muscle contraction is the ratchet movement of the tiny myosin heads toward the centre of thei sarcomere. This ratchet movement occurs many times during muscle contraction.

Points of the sliding filament theory will be as follows :

A bands (contains actin) : Moves close together and do not shorten.I Bands (Distance between A bands of successive sarcomeres) : Decreases in length.H bands (myosin only) : Shortens during contraction.

Actin and myosin filament interactions inside muscle fibers are a component of the sliding filament model of contraction.

Thus, actin filaments slip past myosin filaments after myosin heads connect to them and go through a series of conformational changes. This causes muscle contraction. Sarcomeres, the fundamental contractile units of muscle fibers, shorten as a result of this sliding movement, which causes muscular contraction.

The energy needed for the myosin heads to separate from actin and restart for the following cycle of binding and sliding is provided by ATP. The sliding filament model offers a fundamental knowledge of molecular mechanisms underlying muscle contraction.

What is the most plausible explanation for this?A) The bacterial cell must be resistant to infection by the virus.
B) The virus carries genes that confer resistance to the host bacterial cell.
C) The host bacterium couples the viral infection with transformation.
D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.

Answers

Answer:

D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.

Explanation:

Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.

After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.

Final answer:

The virus entering the bacterial cell's genome in the lysogenic stage explains why new viruses may not lyse new host cells after the initial lysis.

Explanation:

The most plausible explanation for new viruses not lysing new host bacterial cells after initial lysis is D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage. In the lysogenic cycle, the virus incorporates its DNA into the host cell's genome, forming a prophage and establishing a stable relationship with the host without causing immediate lysis. This allows the host cell to continue normal functions until conditions induce the virus to enter the lytic cycle.
