Question

What three steps are included in the breakdown of pyruvate?

a) Glycolysis, citric acid cycle, oxidative phosphorylation
b) Pyruvate decarboxylation, citric acid cycle, electron transport chain
c) Glycolysis, pyruvate decarboxylation, citric acid cycle
d) Citric acid cycle, glycolysis, electron transport chain

Answer 1

The breakdown of pyruvate involves glycolysis, pyruvate decarboxylation, and the citric acid cycle.

Step-by-step explanation:

The breakdown of pyruvate involves three steps:

1. Glycolysis: Glucose is converted into pyruvate.
2. Pyruvate decarboxylation: Pyruvate is converted into acetyl-CoA, releasing carbon dioxide.
3. The citric acid cycle: Acetyl-CoA enters the citric acid cycle, where it undergoes a series of reactions to produce NADH, FADH2, and ATP.
