Which one of the following statements is FALSE A) Complete catabolism of one Ace

Question

Which one of the following statements is FALSE A) Complete catabolism of one Acetyl-CoA that goes through one turn of the citric acid cycle generates 24 ATP. B) One NADH + H^+ is oxidized to NAD^+ and generates 2.5 ATP in the electron transport chain oxidative phosphorylation. C) One FADH_2 is oxidized to FAD and generates 1.5 ATP in the electron transport chain and Oxidative Phosphorylation. D) When one Glucose goes through glycolysis it forms 2 pyruvate, generates 6 ATP, 2 NADH and consumes 2 ATP. E) One Glucose completely oxidized to 6 CO_2 generates 32 ATP in the presence of the element transport chain and oxidative phosphorylation.

Explanation / Answer

Maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP, or sometimes 36 ATP

During ETC (Electron Transport Chain)

10 NADH + 2 FADH2 + 34 ADP + 34 Pi + 6 O2-->34 ATP + 10 NAD + 2 FAD + heat

A) Complete catabolism of Acetyl-CoA in one turn of citic acid cycle generates 36 ATP, not 24 ATP -----> False

B) NADH produces 3 ATP during the ETC (Electron Transport Chain) with oxidative phosphorylation (TRUE)

C) FADH2 produces 2 ATP during the ETC (Electron Transport Chain) (TRUE)

D) One Glucose molecule produces 4 ATP, 2 NADH and 2 pyruvates during glycolysis (TRUE)

E) one glucose completely oxidises to 6 CO2 to generate 34 ATP with 2 ATP is spent for settling the electrons (TRUE)
