Glycolysis

Q1: During glycolysis, the major energy generating step involves

A Phosphofructokinase

B glyceraldehyde-3 -dehydrogenase

C phosphoglycerate kinase

D pyruvate kinase

ANS:C - glyceraldehyde-3 -dehydrogenase

Because these step gives 6ATP.
From step 5 all energy produced is times 2.

In electron transport chain,
1ATP = 1ATP.
1NADH = 3ATP.

Therefore, 2 NADH produced = 3 times 2 = 6.
6ATP.
