How many molecules of O₂ are consumed for each acetyl CoA molecule that enters the common catabolic pathway?

Question

Quizplus · Accepted Answer

Two molecules of O₂ (also known as oxaloacetate) are consumed for each acetyl CoA molecule that enters the common catabolic pathway. This is because the acetyl CoA molecule enters the pathway by first combining with oxaloacetate to form citrate, which then undergoes a series of reactions known as the citric acid cycle (or Krebs cycle). In one round of the cycle, two molecules of CO2 are released, and oxaloacetate is regenerated to start the cycle again. Therefore, each acetyl CoA molecule that enters the cycle requires two molecules of oxaloacetate to complete the cycle.
