How does temperature affect enzyme activity in a chemical reaction?(1 point)

Question

Responses

The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.
The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.

The rate of a chemical reaction initially increases with increasing temperature and continues to increase indefinitely as temperature continues to increase.
The rate of a chemical reaction initially increases with increasing temperature and continues to increase indefinitely as temperature continues to increase.

The rate of a chemical reaction always decreases with increasing temperature and always increases with decreasing temperature.
The rate of a chemical reaction always decreases with increasing temperature and always increases with decreasing temperature.

The rate of a chemical reaction initially increases with decreasing temperature and then decreases, eventually stopping, when the temperature gets too low.

Answer 1

The correct response is:

The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.

This reflects how enzyme activity typically behaves: it increases with temperature up to an optimal point but then decreases and can stop altogether if the temperature is too high, due to denaturation of the enzyme.
