What happens to enzyme activity when temperature rises significantly above its optimum?
A
Activity slows gradually then speeds up
B
Activity remains constant
C
Enzyme is denatured and loses activity
D
Enzyme replicates to compensate
Correct Answer: Option C — Enzyme is denatured and loses activity
Explanation:
When temperature rises significantly above the optimum the enzyme is denatured meaning the active site changes shape so the substrate can no...
When temperature rises significantly above the optimum the enzyme is denatured meaning the active site changes shape so the substrate can no longer bind and activity is permanently lost.
