Question

By what percent (%) will the rate of an enzyme reaction that occurs under normal conditions and has an activation energy of 8.314kj/mol change if it occurs at 37°c? assume that the catalytic activity of the enzyme is the same at the 2 temperatures

Answer 1

The question is incomplete as it lacks the initial temperature, but in general, an increase in temperature usually leads to a higher enzyme reaction rate up to an enzyme's optimal temperature due to a higher proportion of molecules exceeding the activation energy.

Step-by-step explanation:

The question is asking how the rate of an enzyme reaction changes at a different temperature, given that the activation energy is 8.314 kJ/mol and that the reaction occurs at 37°C under normal conditions. This implies using the Arrhenius equation which relates the rate constant of a reaction with temperature and activation energy. Without the initial temperature or rate constant at standard conditions, determining the percent change in reaction rate is not possible. So, the question seems to contain an error or be incomplete as the initial or reference temperature is not provided.

However, under typical conditions and assuming activation energy remains unchanged, the increase in temperature generally leads to an increase in the reaction rate for enzyme reactions, due to more molecules having energy exceeding the activation energy, up to an optimal point beyond which the enzyme may denature and the rate drops again. Temperature effects on enzyme kinetics are significant for applications in medicine and biology, particularly concerning biochemical reactions regulated by enzymes.
