Question

The coenzyme is the oxidizing agent in glycolysis. ADP thiamine pyrophosphate NAD^+ FAD biotin Which of the following represents the net products of glycolysis from one molecule of glucose? 2 pyruvate, 2 NADH, 2 ATP 2 pyruvate, 2 NADH. 4 ATP 3 pyruvate, 2 NADH. 4 ATP 6 CO_2, 30 ATP 6 CO_2, 32 ATP What enzyme catalyzes the major regulatory step of glycolysis? hexokinase aldolase glyceraldehvde-3-phosphate dehydrogenase phosphofructokinase phosphoglucose isomerase In the citric acid cycle, what reduced cofactors are derived from the oxidation of one molecule of acetyl CoA to two molecules of CO_2? 2 NADH and 1 QH_2 3 NADH and 1 QH_2 2 NADH and 2 QH_2 3 NADH and 2 QH_2 4 NADH and 2 QH_2 Glyceraldehyde-3-phosphate dehydrogenase oxidizes an alcohol to a ketone a carboxylic acid to CO_2 an alcohol to an aldehyde an aldehyde to a carboxylic acid an aldehyde to an alcohol

Explanation / Answer

74. Option c

NAD+ is reduced by accepting electrons. It is the oxidizing agent since it causes the loss of electrons from glyceraldehyde-3-phosphate.
