Question

question 5
name the inhibitor of catalase activity.
sodium hydroxide
hydrochloric acid
copper sulfate (cuso4)
ammonium nitrate

Explanation:

Catalase is an enzyme. Heavy metal ions like those from copper sulfate (\(CuSO_4\)) can act as inhibitors. Copper ions (\(Cu^{2+}\)) can bind to the active site of catalase or disrupt its structure through interactions like chelation, reducing its ability to catalyze the decomposition of hydrogen peroxide (\(H_2O_2\)). Sodium hydroxide (\(NaOH\)) and hydrochloric acid (\(HCl\)) mainly affect the pH, and ammonium nitrate (\(NH_4NO_3\)) is not a typical strong inhibitor of catalase in the context of common enzyme - inhibitor interactions.

Answer:

Copper sulfate (\(CuSO_4\))
