Question 14 (4 points) Which one IS NOT the main protein in electron transport chain? a) cytochrome bel complex. O b) citrate synthase O c) cytochrome oxidase. d) NADH dehydrogenase.

Solution

Answer for Q14 : The correct answer is B (Citrate synthase)

Explanation : Citrate synthase is the first enzyme of TCA cycle which catalyses the condensation of acetyl-CoA with oxaloacetate to form citrate.

Answer for Q15 : The correct answer is B.

Explanation : The formation of ATP by phosphoryl group transfer from a substrate such as 1,3-bisphosphoglycerate is referred to as a substrate-level phosphorylation, to distinguish this mechanism from
respiration-linked phosphorylation. For example, The 7^th reaction of glycolysis catalysed by Phosphoglycerate kinase and the 10^th reaction catalysed by Pyruvate kinase are involved in the substrate level phosphorylation.
