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 4 NADH, 4 ATP, 8 CO2, 4 FADH2
net 4 N A D H , 4 A T P , 8 C O sub 2 , 4 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

The correct products of the Krebs cycle after one molecule of glucose (which is converted into two acetyl-CoA molecules) goes through the cycle are:

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

Each acetyl-CoA that enters the Krebs cycle produces:

  • 3 NADH
  • 1 FADH2
  • 1 ATP (or GTP)
  • 2 CO2

Since one molecule of glucose produces 2 acetyl-CoA, the total products will be:

  • 2 acetyl-CoA → 6 NADH
  • 2 acetyl-CoA → 2 FADH2
  • 2 acetyl-CoA → 2 ATP
  • 2 acetyl-CoA → 4 CO2

Thus, the option is 6 NADH, 2 ATP, 4 CO2, and 2 FADH2.
