Question

Predict which temperature –20°c, 39°c, or 50°c– you would expect a human enzyme to function best. plan a simple investigation to test your hypothesis.

A) –20°C
B) 39°C
C) 50°C
D) None of the above

Answer 1

A human enzyme would function best at a temperature around 37°C to 40°C, the normal body temperature. Enzyme activity increases with rising temperature but starts to decrease at temperatures beyond 50°C.

Step-by-step explanation:

The human enzyme would be expected to function best at a temperature around 37°C to 40°C, which is the normal body temperature. Enzyme activity increases as body temperature rises, up to a certain point, and then starts to decrease. Enzymes become less active and can even denature at temperatures beyond 50°C.
