Phosphofructokinase is an enzyme that is able to do what?
A
Phosphorylate a molecule using a phosphate from ATP
B
Breakdown ATP to provide energy to continue glycolysis
C
Synthesize ATP
D
Produce NADH
Verified step by step guidance1
Understand the role of phosphofructokinase in glycolysis: It is a key regulatory enzyme in the glycolytic pathway.
Recognize that phosphofructokinase catalyzes the phosphorylation of fructose-6-phosphate to fructose-1,6-bisphosphate.
Identify that this reaction involves the transfer of a phosphate group from ATP to fructose-6-phosphate, which is a phosphorylation process.
Note that the enzyme does not synthesize ATP; instead, it uses ATP as a substrate to transfer a phosphate group.
Clarify that phosphofructokinase does not produce NADH directly; NADH is produced later in glycolysis during the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate.
