Question

Identify the stages in the Krebs cycle that involve oxidation reaction and the reduction reactions that are coupled to them.

Answer 1

The oxidation reactions in the Krebs cycle involve the conversion of acetyl or carboxylate groups to CO₂, while NAD and FAD are reduced to NADH and FADH₂. These reactions result in the production of reduced electron carriers and a small amount of ATP synthesis.

Step-by-step explanation:

The Krebs cycle, also known as the citric acid cycle, involves several stages that contain oxidation reactions. The oxidation reactions in the Krebs cycle occur when the two-carbon acetyl or four-carbon carboxylate groups are converted into carbon dioxide (CO₂), while the coenzymes NAD and FAD are reduced to NADH and FADH₂. These redox reactions lead to the production of reduced electron carriers and a small amount of ATP synthesis.
