Answer:
a} Allosteric regulation is just any form of regulation where the regulatory molecule (an activator or inhibitor) binds to an enzyme someplace other than the active site.The shape of the active site is changed, allowing substrate to bind at a higher affinity.
b) The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.
c) This is a case of feedback inhibition i in which a product feeds back to shut down its pathways.

21. Which of the following statements about catabolic pathways is false?
a. Carbohydrates can feed into oxidative phosphorylation.
b. Glycogen can be broken down into glucose and feed into glycolysis.
c. Amino acids can feed into pyruvate oxidation.
d. Fatty acids can feed into the citric acid cycle.
Answers
from my point of view I think the answer should amino acid can fit into pyruvate oxidation
Carbohydrates can not feed into oxidative phosphorylation, firstly carbohydrates catabolize through glycolysis and the citric acid cycle and release electrons which feed into oxidative phosphorylation.
What are catabolic pathways?Acetyl-CoA, a chemical that "feeds" the citric acid cycle, can be produced from pyruvate (a byproduct of glycolysis), fatty acid -oxidation, ketone bodies, and amino acid metabolism.
The citric acid cycle is "cataplerotic" when molecules from other routes enter it for catabolism. Amino acids catalyze the breakdown of pyruvate.
Alanine, serine, glycine (through serine), and cysteine are among the amino acids with three carbon atoms that are transformed into pyruvate (the entry point for the citric acid cycle or gluconeogenesis)
Therefore, carbohydrates can feed into oxidative phosphorylation is false about the catabolic pathway, hence option A is correct.

C. On average, about 10 percent of available energy is transferred from one trophic level to the next.
D. Among consumers in an ecosystem, first-level consumers have the most available energy
Explanation:
The number of trophic levels are limited. when one available energy is transferred from one trophic level to another trophic level, about 10 percent of energy is transferred whereas the rest of the energy about 90 percent is released in the form of heat energy. The first-level consumers have the most available energy due to higher biomass.

This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

Every single cell organism is able to survive because it carries out
Answers
Every single cell of an organism is able to survive independently because it carries out metabolic processes at its own.
What is Metabolism?Metabolism can be defined as the chemical changes or reactions which take place in a cell or an organism. These changes make energy and the compounds which cells and organisms need to grow, reproduce, and stay healthy.
Metabolism is divided into two classes: anabolism and catabolism. Anabolism involves the synthesis of a complex compound from simpler or smaller molecules or atoms. Catabolism involves the breakdown of a complex molecule into smaller and simpler ones.
Living organisms are able to perform the metabolic processes such as respiration, excretion, reproduction, and digestion which is a distinguishing factor from that of non-living organisms.

All organisms utilize adenosine triphosphate (ATP) as their major source of energy. The molecules
of ATP and ADP (adenosine diphosphate) + P: (inorganic phosphate) form a cycle to allow for a
constant source of energy-rich ATP molecules.
Which of the following MOST accurately describes the role of ATP as a source of energy?
O ATP absorbs energy as it is converted into ADP + Pi.
ADP + P; release energy as they are converted into ATP.
O When ATP is converted into ADP + Pi , energy is released and used by the cell.
O When ADP + Pi are converted into ATP, energy is released and used by the cell.
Answers
Answer:
When ATP is converted into ADP + P energy is released and used by the cell.
Explanation: ATP contains energy, when a certain part breaks off it converts into ADP and releases energy for the cell tp use.
When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.
What is ATP?An organic substance called adenosine triphosphate (ATP) gives energy to a variety of biological functions in living cells, including muscular contraction, nerve impulse transmission, condensate dissolving, and chemical synthesis.
ATP is frequently referred to as the "molecular unit of currency" of intracellular energy transfer and is present in all known forms of life. It either transforms into adenosine monophosphate (AMP) or adenosine diphosphate (ADP) when absorbed in metabolic activities (AMP).
ATP is replenished by other processes. Every day, the human body recycles the equivalent amount of ATP to its own body weight. Additionally, it serves as a coenzyme and a precursor to DNA and RNA.
Therefore, When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

Answers
Answer:
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg
Explanation:
This question can be reframed in the manner below for better understanding.
If 1.5 oz or ounce of a chocolate bar contains 6 mg of caffeine, how many milligrams (mg) of caffeine is contained in 85 grams of the same chocolate bar.
Firstly, the ounce should be converted to grams
If 1 ounce = 28.35g
1.5 ounce = ?
= 1.5 × 28.35/1
=42.53g
Hence, 42.53g of the chocolate bar contains 6 mg of caffeine
85g of the chocolate will contain
42.53g = 6mg
85g = X
where X is the amount of caffeine that will be consumed in mg
X = 85 × 6/42.53
X = 11.99 mg
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.
