Concept covered: recap and review answer each question to complete this review of all the stages of respiration
Cellular respiration involves converting energy from nutrients into ATP with waste products being released, occurring over three stages: glycolysis, the Krebs cycle, and the electron transport chain. The mitochondrion is vital for these processes. Respiration refers to breathing and includes ventilation and gas exchange, differing from cellular respiration, which is a metabolic process in cells.
Explanation:Cellular respiration is a set of metabolic reactions used by cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The three stages of cellular respiration are glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain.
The mitochondrion is a double-membraned organelle that plays a critical role in cellular respiration by hosting the citric acid cycle and electron transport chain. The large surface area provided by its highly folded inner membrane is critical for the reactions of cellular respiration that produce ATP.
For an organism lacking mitochondria, it would use a form of respiration such as fermentation, which does not require mitochondria and occurs in the cytoplasm.
The water vapor that condenses on a cold window pane when you exhale comes from the lungs as they expel water vapor that is a byproduct of cellular respiration.
Differentiating Between Respiration and Cellular Respiration
Respiration generally refers to breathing which involves the inhalation of oxygen and exhalation of carbon dioxide. It consists of two parts: ventilation and gas exchange. Cellular respiration, while related to breathing, refers explicitly to the biochemical process within cells that converts nutrients into energy.
Aerobic respiration is a type of cellular respiration that uses oxygen to produce ATP. The overall chemical reaction for aerobic respiration is C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + energy (ATP). The four stages of aerobic respiration are glycolysis, the transition reaction, the Krebs cycle, and the electron transport chain and oxidative phosphorylation.

A high rate of evaporation and condensation in the water cycle can most likely cause
a. floods
b. blizzards
c. earthquakes
d. hurricanes
A high rate of evaporation and condensation in the water cycle can most likely cause hurricanes. This is because these conditions imply the transfer of a lot of heat energy, which can fuel the development of severe weather systems like hurricanes.
Explanation:A high rate of evaporation and condensation in the water cycle can most likely cause hurricanes (option d). The water cycle involves the continual movement of water on, above, and below the surface of the Earth. During this cycle, water changes states among liquid, vapour, and ice. As part of this process, heat is transferred from the Earth's surface to the atmosphere, creating conditions for weather phenomena. When there is a high rate of evaporation and condensation, it means there is a lot of heat energy being transferred which can spur the development of severe weather systems like hurricanes. Hurricanes are essentially large, organized systems of thunderstorms and require warm, moist air as fuel, which is provided by the high rates of evaporation and condensation.

By which process do plants lose their water to the atmosphere? sublimation transpiration condensation precipitation
Answer:
The correct answer is: transpiration.
Explanation:
All of the options are parts of the water cycle.
The process in which plants lose their water to the atmosphere is called transpiration. Transpiration consists of the evaporation of water through pores in their leaves. Transpiration is beneficial for the plants as it assists them in photosynthesis.
Sublimation refers to the transition of water from solid state to gas state, without passing through the liquid state that is normally in between those phases.
Condensation is the change of water from a gas state to a liquid state. Condensation is followed by Precipitation, a process in which water in the liquid state falls from the skies, like when it's raining.

The enzyme amylase in human saliva breaks down starch polymers into smaller sugar units. however, it cannot break down cellulose polymers. both are made of glucose monomers, but in cellulose the monomers are linked together in a different shape than in starch. why can't amylase digest cellulose
Amylase cannot digest cellulose because the beta 1-4 glycosidic bonds in cellulose have a different stereochemistry than the alpha 1-4 glycosidic bonds in starch. While amylase works on starch, it is not configured to interact with cellulose, which instead passes through the digestive system as fiber.
The enzyme amylase is responsible for the breakdown of starch polymers like amylose into smaller sugar units like glucose and maltose. Amylose is a polysaccharide made of glucose monomers linked by alpha 1-4 glycosidic bonds. Salivary amylase can cleave these specific bonds, which are in a 'straight' configuration, allowing for the digestion of starch starting in the mouth and continuing in the small intestine.
However, cellulose is a different kind of polysaccharide also made of glucose monomers, but here, the monomers are linked by beta 1-4 glycosidic bonds. This different bond results in a 'flipped' stereochemistry compared to the alpha linkage in starch. Enzymes, including amylase, are highly specific and sensitive to the structure of the molecules they act on. As a result, the enzyme amylase cannot break the beta 1-4 glycosidic bonds in cellulose due to their different stereochemistry. While amylase facilitates starch digestion, it is ineffective on cellulose, which passes through the human digestive system as dietary fiber. Other enzymes such as cellulases found in nature can break down cellulose, but humans do not produce these enzymes.

Explain why a forest fire is considered to be a density-independent limiting factor.
A forest fire is considered to be a density independent limiting factor because there will be no effect in the outcome whether there are organisms or however many are there involved in which the forest fire can’t be changed regardless of how many are the population is—this pertains to the density independent.
A forest fire is a density-independent limiting factor, meaning it affects population mortality irrespective of population density. Unlike density-dependent factors, which vary based on population size, density-independent factors like forest fires will have the same effects regardless of how many individuals are present. These factors are essential to understanding population regulation.
Explanation:A forest fire is considered to be a density-independent limiting factor because it affects the mortality of a population regardless of its density. This means that the forest fire will cause death and destruction independent of whether the population density is high or low. For example, if a deer population inhabits the forest, individuals will be killed in the fire, irrespective of how many deer are present in the area.
Density-independent factors, like a forest fire, typically are abiotic and can include things like weather conditions, natural disasters, and pollution. Contrast this with density-dependent factors, which have different effects depending on the population density. One example of a density-dependent factor is food availability, which becomes a limiting factor when a population, such as caterpillars, becomes too large for the food supply to support.
It's crucial to understand the distinction between these two factors and how they interact in order to comprehend how an environment can regulate its population numbers. Indeed, understanding situations in which density-dependent and density-independent factors interact is especially complex and important. For instance, a dense population reduced by an environmental factor like a forest fire may recover differently than a sparse population.

how do organisms obtain and use the energy they need to live and grow
Organisms obtain and use energy through cellular respiration and photosynthesis.
Explanation:Energy is a fundamental requirement for all living organisms, and essential for various biological processes. Organisms obtain and use the energy they need to live and grow through a process called cellular respiration. This process involves breaking down organic molecules, such as glucose, to release energy in the form of adenosine triphosphate (ATP).
Autotrophs, like plants, obtain energy through photosynthesis by converting sunlight into chemical energy. Heterotrophs, including animals and fungi, obtain energy by consuming other organisms. This energy is then used for growth, reproduction, movement, and maintenance of vital functions, ensuring the organism's survival and well-being as well.

A lab rat had part of its hypothalamus destroyed. the rat seems to have lost all interest in food and won't eat even when food is available. it would appear that part of the _____ has been destroyed.
Final answer:
Damage to the lateral hypothalamus (LH) in a lab rat's brain likely caused the loss of interest in food, as the LH is integral for initiating hunger.
Explanation:
The lab rat that had part of its hypothalamus destroyed and subsequently lost all interest in food likely had damage to its lateral hypothalamus (LH). The LH is a crucial area in the brain for initiating hunger. Lesions in the LH can cause animals to lose their desire to eat, leading to self-starvation if not force-fed. Conversely, stimulating the LH can induce eating behavior when food is present. It contrasts with another region of the hypothalamus, the ventromedial hypothalamus (VMH), which is responsible for signaling satiety or the feeling of fullness that stops eating behavior.

How does a catalyst speed up chemical reactions?
Answer:
By lowering down the activation energy.
Explanation:
Activation energy is the energy required to transform the substrate into the high energy state that is eventually converted into the product. High energy requirement in the form of activation energy does not allow the reactions to occur at a higher rate under room temperature.
Catalysts are the substances that speed up the chemical reaction by lowering down the activation energy. The reduced energy requirement allows the reactions to occur at higher rates in presence of catalysts.
