Question

What is the term that describes when an enzyme’s active site changes shape?

A: synthesis

B:optimum

C: decomposition

D: denature

Answer 1

Denature

as

when something causes the enzyme to change shape, thus changing shape of the active site and not allowing any substrate molecules to fit in the site and bind. Denaturation makes it so reactions don't occur between the substrate and the enzyme

Answer 2

Denature
Answer D

This is because the hydrogen bond is broken causing the active site to become denatured
It can be caused by very high temperature beyond optimum temperature
