what is the fate of pyruvic acid in an organism that uses aerobic respiration?
it is reduced to lactic acid
it is oxidized in the electron transport chain
it is catabolyzed in glycolysis
it is converted to acetyl coa
question 2 (bonus) (1 point) ✓ saved
the majority of atp synthesis in cellular respiration occurs during:
glycolysis
electron transport chain
fermentation
krebs cycle

Explanation:

In aerobic respiration, pyruvic acid enters the mitochondria and is converted to acetyl - CoA in the link reaction. For the second question, the majority of ATP synthesis in cellular respiration occurs during the electron - transport chain through oxidative phosphorylation. Glycolysis produces a small amount of ATP, fermentation is an anaerobic process, and the Krebs cycle also contributes ATP but not as much as the electron - transport chain.

Answer:

Question 1: it is converted to acetyl CoA
Question 2: Electron Transport Chain
