Question

A human digestive enzyme breaks down its substrate at a fast rate at 35 °C.

What would occur if the enzyme and substrate were kept at 75 °C?
A The enzyme would stop working and be denatured.
B The reaction would continue at the same rate.
C The reaction would take place more quickly.
D The reaction would take place more slowly.
Thank you!
