Answer 1

Answer:

Q.1)

a) the process of breaking down of a single glucose molecule to yield 38 units of energy storing ATP molecules in known as aerobic respiration.

b) The process of anaerobic respiration is relativity less energy-yielding as compared to the aerobic respiration.

sorry I know only this much.

hope this will help you

Answer 2

Answer:

Q.1)

a) Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. In contrast, anaerobic respiration does not use oxygen.

b)Anaerobic respiration is the type of respiration through which cells can break down sugars to generate energy in the absence of oxygen. This is in contrast to the highly efficient process of aerobic respiration, which relies on oxygen to produce energy.

Q.2)

Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytosol of the cell cytoplasm, in the presence or absence of oxygen.

Q.3)

• The Krebs cycle, also known as the citric acid cycle or TCA cycle is a series of reactions that take place in the mitochondria resulting in oxidation of acetyl CoA to release carbon dioxide and hydrogen atoms that later lead to the formation of water.
• The cycle is termed the citric acid cycle as the first metabolic intermediate formed in the cycle is citric acid.
• This cycle is also termed tricarboxylic acid (TCA) because it was then not certain whether citric acid or some other tricarboxylic acid (g., isocitric acid) was the first product of the cycle. However, now it has been known that the first product is indeed citric acid and thus the use of this name has since been discouraged.
• This cycle only occurs under aerobic conditions as energy-rich molecules like NAD+ and FAD can only be retrieved from their reduced form once they transfer electrons to molecular oxygen.
• The citric acid cycle is the final common pathway for the oxidation of all biomolecules; proteins, fatty acids, carbohydrates. Molecules from other cycles and pathways enter this cycle through Acetyl CoA.
• The citric acid cycle is a cyclic sequence of reactions formed of 8 enzyme-mediated reactions.
• This cycle is also particularly important as it provides electrons/ high-energy molecules to the electron transport chain for the production of ATPs and water.
• Pyruvate formed at the end of glycolysis is first oxidized into Acetyl CoA which then enters the citric acid cycle.
