Question

Which of the following is the common product produced during aerobic and anaerobic respiration initially in the first step?

• A. Water
• B. Pyruvate
• C. Lactic acid
• D. Ethanol

Answer 1

Answer:

B. Pyruvate

• Both aerobic and anaerobic respiration begin with glycolysis, which produces pyruvate as the initial common product

• Glycolysis is a common phase between aerobic and anaerobic respiration. Glycolysis is also called the EMP pathway.

• It is the metabolic pathway that converts glucose into pyruvic acid.

• This pathway does not require oxygen.

• The energy released in the process forms the high-energy ATP (adenosine triphosphate) molecules.

• It also reduces NADH (nicotinamide adenine dinucleotide).

• It is a sequence of ten reactions that are catalyzed by enzymes.

• The final product of glycolysis is lactate in anaerobic respiration and pyruvate in Aerobic respiration.
