Pyrimidines are synthesized through a long series of reactions beginning with the amino acid aspartate. The ribonucleotide CTP is one of the final compounds in this reaction pathway, and when the cell has enough CTP, it binds to and inhibits the enzyme that catalyzes the first reaction in the pathway, aspartate transcarbamoylase (ATCase). This is most likely an example of:

A. Copmetitive inhibition

B. Allosteric acivation

C. Allosteric inhibition

D. Direct feedback inhibition

E. End-product inhibition

F. Both allosteric inhibition

G. Both competiteve inhibition

Know the Answer?

Zachary Hebert · Answer 1

the correct answers is E

Explanation:

the inhibition of the enzyme by increasing the concentration of the final product is called "End production inhibition".

This is because they are negative feedback systems, where they must have an end of cycle, that is why the products inhibit the start of the reagents or their enzymatic activation.

Mariela Anderson · Answer 2

The Correct option is E "End-product inhibition"

Explanation:

the given model is both allosteric hindrance and final result restraint. This is on the grounds that allosteric hindrance is said when the higher centralization of finished result is dependable to give the sign to stop the combination. As the finished result is restraining the combination of its own so it can likewise be called a final result restraint.

Henceforth, the right choice is (E).
