all of the following that correctly describe some aspect of step 3
in glycolysis.
Choose one or more:
A.The reaction generates the product fructose 1,6-bisphosphate.
B.The enzyme uses an ATP.
C.The reaction is an irreversible reaction.
D.The enzyme that catalyzes step 3 is
phosphofructokinase.
Homework Answers
PART 1
- Energy is invested by using up some ATP
- The six carbon sugar is split into two smaller molecules
- Energy is captured as ATP and NADPH
- Two molecules of pyruvate are generated
PART 2
A,B,C,D
All of the part correctly describes the STEP 3 of glycolysis
STEP 3 is carried out by Phosphofructokinase which converts Fructose-6-phosphate into Fructose-1,6-bisphosphate utilising ATP as energy source. This step is irrevesible

please explain answer
Glycolysis. In the third step of glycolysis, the enzyme phosphofructokinase transfers a phosphate group from ATP to fructose-6-phophate to generate fructose- 1,6- bisphosphate. In contrast, in step 10, the enzyme pyruvate kinase transfers a phosphate group from phosphoenolpyruvate to ADP to generate ATP. Using what you know about the standard free energy change associated with phosphate bonds, (briefly) explain why we observe this difference.
