1 answer

The Krebs cycle, also known as the citric acid cycle or TCA cycle, processes one molecule of glucose (which is converted into two molecules of acetyl-CoA). For each cycle of the Krebs cycle that is completed with acetyl-CoA, the following products are produced:

  • 3 NADH
  • 1 FADH2
  • 1 ATP (or GTP, depending on the cell type)
  • 2 CO2

Since one molecule of glucose results in two rounds of the Krebs cycle (one for each acetyl-CoA), you would multiply these products by two:

  • 6 NADH
  • 2 ATP
  • 4 CO2
  • 2 FADH2

Therefore, the correct answer is: 6 NADH, 2 ATP, 4 CO2, and 2 FADH2.
