Which of the following represents an irreversible step in glycolysis?

A) 1,3 – bisphosphoglycerate to 3 - phosphoglycerate
B) Fructose 6 – phosphate to fructose 1,6 - bisphosphate
C) Fructose 1,6 – bisphosphate to glyceraldehydes 3 – phosphate
D) Glucose 6 – phosphate to fructose 6 – phosphate
E) Glyceraldehyde 3 – phosphate to 1,3 – bisphosphoglycerate

I'd go with B, just because its a rate limiting step

B

its a B) Fructose 6 - phosphate to fructose 1,6 - bisphosphate

yup its fructose 6 phosphate ------ fructose 1 6 bisphosphate


the other 2 irreversible steps in glycolysis are glucose ---- glucose 6 phophate

phophoenol pyruvate ----- pyruvate



if it is a rate limiting step is it a irrevesible step for sure ???/ i dont think so explain
