Temperature Effects on Enzyme Activity

Medium Biochemistry Enzymes

Enzymes are biological catalysts that significantly increase the rate of chemical reactions in biological systems. They operate by lowering the activation energy required for a reaction to proceed, allowing the reaction to progress more efficiently. Each enzyme is specific to its substrate because of the unique three-dimensional structure that forms its active site.

Consider the following scenarios regarding enzyme activity and specificity:

Which of the following statements is true regarding the effect of temperature on enzyme activity?

Increasing temperature always increases enzyme activity.

Enzymes become denatured at lower temperatures.

There is an optimal temperature range where enzyme activity is maximized.

All enzymes function best at the same temperature.
