Question

For the following question, please answer each question and explain how you arrived to the answer. Please do not give me the pathway for glucose. I would like to know what would happen in the following pathway.

A catabolic pathway exists for compound A, proceeding to compound F in 5 steps. Compound F proceeds through either an aerobic three step pathway to Compound I or a two step pathway to compound K. Compound F is a feedforward activator for the enzymes that catalyze the formation of both I and K. Compound G is a feedback inhibitor for the initial enzyme in the joint pathway and compound J is a feedback inhibitor for the enzyme that produces F.

a). Draw a diagram showing the regulation of this pathway.

b). If ATP is involved in regulation of the pathway above in question a, should it be an inhibitor or an activator? Why?

c). Where in the reaction pathway from question (a) should the regulation of ATP from question (b) take place? Why?

Explanation / Answer

a)

b) ATP can be involved from the step F to I or K which is a positive regulation or it can be involved in the step of J which is a negative feedback regulation

C) ATP involvement could be involved in the step F or J
