How many NADH are produced in one complete cycle of the citric acid cycle?
Understand the Problem
The question is asking how many NADH molecules are produced during one complete cycle of the citric acid cycle, which is a key part of cellular respiration. It requires knowledge of biochemistry to answer correctly.
Answer
3 NADH molecules.
The citric acid cycle produces 3 NADH molecules per cycle.
Answer for screen readers
The citric acid cycle produces 3 NADH molecules per cycle.
More Information
The citric acid cycle, also known as the Krebs cycle, generates 3 NADH per acetyl-CoA molecule due to specific enzyme-catalyzed reactions that involve oxidative decarboxylation and the reduction of NAD+ to NADH.
Tips
A common mistake is confusing the number of NADH produced per cycle with total numbers from glucose metabolism, where two cycles are completed per glucose molecule.
