A Mutation occurred within the Dna sequence coding for an enzyme, causing a decrease in the rate of a reaction catalysed by this enzyme.Which statement could explain the decrease in rate of reaction?

1. Inhibitor for this enzyme has an increased affinity for the enzyme and formed an enzyme-inhibitor complex more easily

2. The active site of the enzyme might have changed shape and so is no longer complementary.

3. The activation energy for the reaction with the mutated enzyme is greater than with the non-mutated enzyme.

Answer is C 1 and 3 only with 1 2 and 3 as option A.

Also huge shoutout to my biology teacher for seening all my messages and questions for the past few months, thanks for ntg mr. william
