Answer 1

The Krebs cycle (also known as the citric acid cycle or TCA cycle) processes one glucose molecule resulting in the following products:

• For every glucose molecule that enters glycolysis, two molecules of pyruvate are produced. Each pyruvate then enters the Krebs cycle.
• Each turn of the cycle produces:
  • 3 NADH
  • 1 FADH2
  • 1 ATP (or GTP, depending on the organism)
  • 2 CO2

Since one glucose molecule generates two pyruvate molecules, the cycle turns twice. Therefore, the overall products after one molecule of glucose goes through the Krebs cycle would be:

• 6 NADH
• 2 FADH2
• 2 ATP
• 4 CO2

Thus, the correct response is: 6 NADH, 2 ATP, 4 CO2, and 2 FADH2.
