Detailed explanation-1: -Two molecules of acetyl-CoA are produced from each glucose molecule so two turns of the Krebs cycle are required which yields four CO2, six NADH, two FADH2 and two ATPs.
Detailed explanation-2: -Thus, one acetyl CoA forms one ATP molecule. Hence, the two will form 2 ATP molecules in one cycle of the Krebs cycle.
Detailed explanation-3: -Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles.
Detailed explanation-4: -Each glucose molecule produces two acetyl-CoA, fueling two turns of the Krebs cycle and doubling these amounts. The net products of glycolysis are 2 pyruvate, 2 ATP, and 2 NADH.
Detailed explanation-5: -Two acetyl-CoA molecules enter the cycle, and each has two carbon atoms, so four carbon dioxide molecules will form.
