The Krebs cycle forms many products. Which option lists the correct products of the Krebs cycle after 1 molecule of glucose goes through it?(1 point) Responses net 1 NADH, 1 ATP, 2 CO2, 1 FADH2 net 1 N A D H , 1 A T P , 2 C O sub 2 , 1 F A D H sub 2 net 2 NAD+, 2 ATP, 4 CO2, 2 FADH net 2 N A D plus , 2 A T P , 4 C O sub 2 , 2 F A D H 6 NADH, 2 ATP, 4 CO2, and 2 FADH2 6 N A D H , 2 A T P , 4 C O sub 2 , and 2 F A D H sub 2 net 4 NADH, 4 ATP, 8 CO2, 4 FADH2

Answer 1

The correct response for the products of the Krebs cycle (also known as the citric acid cycle) after one molecule of glucose (which yields two acetyl-CoA molecules) has gone through it is:

6 NADH, 2 ATP, 4 CO2, and 2 FADH2.

Here's a brief breakdown:

• Each glucose molecule produces 2 acetyl-CoA, which then enters the Krebs cycle.
• For each acetyl-CoA that enters the cycle, the results are:
  • 3 NADH
  • 1 ATP (or GTP, depending on the tissue)
  • 2 CO2
  • 1 FADH2

Thus, for two acetyl-CoA molecules (from one glucose), you would get:

• 6 NADH (3 per acetyl-CoA x 2)
• 2 ATP (1 per acetyl-CoA x 2)
• 4 CO2 (2 per acetyl-CoA x 2)
• 2 FADH2 (1 per acetyl-CoA x 2)

So the total products after one glucose undergoes the Krebs cycle are indeed 6 NADH, 2 ATP, 4 CO2, and 2 FADH2.
