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
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

net 1 NADH, 1 ATP, 2 CO2, 1 FADH2

Answer 1

The correct answer is:

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

When one molecule of glucose goes through the Krebs cycle (also known as the citric acid cycle or TCA cycle), the energy yield includes 6 molecules of NADH, 2 molecules of ATP (or GTP, depending on the specific cell type), 4 molecules of CO2, and 2 molecules of FADH2 during two turns of the cycle, as each glucose molecule is split into two molecules of pyruvate that enter the Krebs cycle.
