1 - Which molecule is an allosteric inhibitor or aspartate transcarbamoylase (ATC)? Explain why it makes sense that this molecule inhibits ATC and not the immediate product of the reactions catalyzed by ATC. Explain how the inhibition works structurally, with catalytic and regulatory subunits of ARC.

Succinyl-CoA is a negative regulator of citrate synthase. Explain why this makes sense, and propose a possible mechanism for how this molecule inhibits citrate synthase. What other step of the citric acid cycle is inhibited by succinyl-CoA, and how do you expect that inhibition mechanism to be similar/different?

Question 1 2 pts How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction? by decreasing the free-energy change of the reaction catalyzed by the enzyme by binding to an allosteric site, thus changing the shape of the active site of the enzyme by binding to the active site of the enzyme, thus preventing binding of the normal substrate by binding to the substrate, thus changing its shape so that it no longer binds to the active site...
