← ScienceWhich consequence results when an enzyme deactivates prematurely?
A)Metabolic pathway rate decreases drastically✓
B)Transition state energy level increases
C)Substrate molecules tightly bind the catalyst
D)Product inhibition becomes rapidly attenuated
💡 Explanation
Deactivation reduces available enzymes; therefore, the metabolic pathway has fewer catalysts to lower activation energy and speed up the reaction. This catalytic inefficiency means the metabolic pathway rate severely falls, because it lacks facilitation, rather than other regulatory alterations.
