Question

a genetic mutation causes the three - dimensional shape of a photosynthetic enzyme to change, but the active site is unaffected. which of the following is likely the result? there would be no effect on normal enzyme function. the associated metabolic reaction takes more energy. the enzyme now must use an induced fit reaction. this enzymes shape is not affected by ph. the substrate molecules cannot attach to the enzyme.

Explanation:

Enzymes function based on their active - site structure. If the active site is unaffected by the shape - change due to mutation, normal function is likely not affected. The shape of an enzyme is pH - sensitive in general, and since the active site is okay, substrate can bind as usual. Induced fit is a normal mechanism and not a result of this mutation. A change in shape without active - site alteration usually doesn't increase the energy requirement of the associated reaction.

Answer:

There would be no effect on normal enzyme function.
