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: -Answer and Explanation: For each turn of the citric acid cycle there are three molecules of NADH + H+ produced.
Detailed explanation-3: -Results of the Krebs Cycle These molecules are: 4 ATP (including 2 from glycolysis) 10 NADH (including 2 from glycolysis)
Detailed explanation-4: -Step 8 of the Krebs cycle: Malate-Dehydrogenase This final reaction closes the krebs cycle. here, L-malate is transformed into oxal acetate. The hydroxy group of L-malate (in yellow) is oxidized to an -keto group and the released protons are picked up by NAD+, which then is reduced to NADH + H+.
Detailed explanation-5: -Solution: 3 molecules of NADH2 and 1 molecule of FADH2 are formed by two turns in Kreb’s cycle but by one turn, zero number of NADPH2 are formed. Krebs cycle is a second phase of aerobic respiration during which acetyl CoA condenses with OAA to form citrate which undergoes oxidative decarboxylation.
