Answer to Question #336553 in Organic Chemistry for Cheers

Question

Most of steps in glycolysis are reversible by the same enzyme. However, there are 3 steps in the pathway that cannot be reversed by the same enzyme.

a) What are the general terms used in describing (i) these steps and (ii) the enzymes catalysing these steps?​​​​​​​

b) Name these enzymes and show the steps in the pathway that they catalyse.​

c) Indicate how these steps in glycolysis are reversed in gluconeogenesis.​

d) Why can glycolysis and gluconeogenesis take place in two different tissues at the same time but not in the same tissue at the same time?​​​​
