Chemistry
1 answer:
Yanka [14]3 years ago

Answer:

A

Explanation:

A catalyst refers to an enzyme composed of peptides in their tertiary conformation.  

The addition of a catalyst provides a new path to the reaction and the reaction proceeds in a faster way compared to the reaction without a catalyst.

The peptides are arranged in such a way that they form a pore-like structure which allows the binding of the substrate molecules by forming a temporary covalent bond. These bonds lower the activation energy of the complete reaction which is required to initiate a reaction.

In the given diagram, the activation reaction is represented by the letter "A" and therefore a catalyst will lower and alter the value of A.

Thus, Option-A is correct.
