Assertion. Homoeothermy provides faster metabolism.
Reason. Enzyme action quickens with rise in temperature.

Rate of a reaction increases with the rise of temperature. The reason is

Assertion (A) : Heat energy is transferred from one body to another due to a temperature difference between them. Reason (R) : Heating a substance causes a rise in temperature.

Assertion. There is no mechanism in a cell to control enzyme action. Reason. Enzymes do not require any control mechanism.

Assertion (A) : Equilibrium constant of a reaction increases if temperature is increased Reason (R) : The forward reaction becomes faster with increase of temperature.

Explain the effect of temperature on enzyme action.
