Question

52 Carbon dioxide (co2) is released during which the following stages of cellular respiration? of A) glycolysis and the oxidation of pyruvate to acetylCoA B) glycolysis and the citric acid cycle C) the citric acid cycle and oxidative phosphorylation D) oxidation of pyruvate to acetyl CoA and the citric acid cycle 53) In the complete reactions of a respiration, the energy for the majority of ATP synthesis is provided by A) the production of carbon dioxide and oxygen in the electron transpo E) transfer of electrons from organic molecules to intermediates in the citric acid cycle. C) high-energy phosphate bonds from organic molecule D) a proton gradient across a membrane. 5) Where are the proteins of the electron transport chain located? B) inner mitochondrial membrane A) mitochondrial intermembrane space D) mitochondrial matrix C) outer mitochondrial membrane Acetyl CoA. Oxaloacetate NADH Citrate NAD Isocitrate Malate CO.

D) 12 B 2 A) 1

Explanation / Answer

52. The correct option is D , i.e. oxidation of pyruvate to acetyl coA and citric acid cycle.

53. The correct option is D , i.e.a proton gradient across a membrane .

54.The correct option is B , i.e. inner mitochondrial membrane.

55.The correct option is A , i.e. 1.

56.The correct option is A , i.e. Oxaloacetate will accumulate and citric acid will decrease.

57. The answer should be 12 , i think option A must be miss print.

58. The correct option is A , i.e. Inner Membrane.
