Answer:
The intracellular chemical reaction will proceed at a slower rate.
Explanation:
Enzymes are proteinous substances referred to as "biological catalyst". Enzymes catalyze biochemical reactions by increasing the rate at which the reaction occurs. They do this by lowering the activation energy needed for the reaction to start.
Since enzymes speed up the rate of chemical reactions, an absence of such enzyme or its non-functionality will result in such reaction proceeding at a slower rate.
