Question 4

A patient's blood sample is being analyzed for enzyme activity. Which of the following factors, if significantly altered, would most directly lead to the denaturation of an enzyme and loss of its catalytic function?

Accepted Answer

C. Optimal pH deviation — Enzymes are proteins whose catalytic activity is highly dependent on their specific three-dimensional structure. Significant deviation from the optimal pH or temperature can cause denaturation, leading to the unfolding of the enzyme and loss of its active site, thereby abolishing its catalytic function. Substrate concentration, product accumulation, and presence of cofactors primarily affect the rate of enzyme activity rather than causing denaturation.

A. Substrate concentration
