Impact of Temperature and pH on Catalase Activity

Very Hard Biochemistry Enzymes

Enzymatic activity is crucial for facilitating biochemical reactions within living organisms. An enzyme, catalase, is known for its ability to decompose hydrogen peroxide into water and oxygen. Consider the effects of various factors on enzyme kinetics. A recent study examined the impact of temperature and pH on the activity of catalase. The researchers discovered the following:

Increased temperature up to 37°C enhanced enzymatic activity, but activity sharply declined at temperatures above 50°C.
The optimal pH for catalase activity was determined to be around 7, with significant inhibition at acidic pH levels.

Based on these observations, which of the following statements correctly interprets the effects of temperature and pH on catalase enzymatic activity?

Catalase activity increases linearly with temperature, regardless of pH.

A drop in catalase activity at high temperatures indicates denaturation.

Catalase is inactive at neutral pH but functional at acidic pH levels.

Optimal catalase activity is observed at temperatures above 50°C.
