34. Which statement about glycolysis is true?
1. The phosphorylation of fructose 6-phosphate to fructose-1,6-bisphosphate is the committed step in glycolysis because fructose 1,6-bisphosphate can undergo no other reactions than those of glycolysis.
2. The enzyme catalyze the phosphorylation of fructose 6-phosphate to fructose-1,6-bisphosphate is activated only when cells need pyruvate.
3. NADH is the cozezyme for glyceraldehyde-3-phosphate dehydrogenase.
4. During glycolysis, ATP use and production is exactly even after the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate

(C) 1 and 4 are true.
(D) 2 and 3 are true.
