The Krebs cycle begins with:
Correct answer: A. Acetyl-CoA
- A. Acetyl-CoA
- B. Hydrochloric acid
- C. Lysine
- D. PGA
Explanation
The Krebs Cycle starts with the combination of acetyl-CoA, a two-carbon compound derived from the breakdown of pyruvic acid in glycolysis or fatty acids in beta-oxidation, with oxaloacetic acid, a four-carbon compound. This condensation forms citric acid, a six-carbon compound, initiating the Krebs Cycle.
