HELP ME PLEASE
A cellular enzyme is effectively deactivated by an increase in temperature of 10°C. Which is the most likely mechanism of the deactivation?

A. The enzyme, which is a carbohydrate, breaks apart into glucose molecules.
B. The enzyme, which is a protein, breaks apart into individual amino acids.
C. The enzyme changes shape and is no longer able to bind the substrate.
D. The enzyme reacts with the substrate to produce side products.

The answer is; C

When the temperatures are increased, the protein structure is destabilized because the essential hydrogen bonds between amino acid residues that maintain the protein structure begin to be broken. This is called denaturing of the protein. The protein loses shape and the active site is distorted causing the enzyme to be unable to bind to its substrate.
