Pyruvate, the end product of glycolysis moves from cytosol to mitochondrial matrix where it is oxidized into _ producing CO2 as a by-product.
Correct answer: A. Acetic acid (active)
- A. Acetic acid (active)
- B. Citrate
- C. NAD
- D. FAD
Explanation
Pyruvate, the end product of glycolysis, moves from the cytosol to the mitochondrial matrix, where it undergoes oxidative decarboxylation. During this process, pyruvate is converted into Active Acetic acid or acetyl-CoA (acetyl coenzyme A). The reaction involves the removal of a carbon dioxide (CO2) molecule as a by-product. This step is known as the pyruvate decarboxylation reaction. The acetyl-CoA then enters the citric acid cycle (also known as the Krebs cycle) within the mitochondrial matrix.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
