Question

Which of the following graphs explains the effect of pH on the enzyme activity?

A

Graph 1

B

Graph 2

C

Graph 3

D

Graph 4

Step-by-Step Solution

According to the text, enzymes generally function in a narrow range of pH. Each enzyme shows its highest activity at a particular pH called the optimum pH. Activity declines both below and above the optimum value, producing a bell-shaped curve . Figure 9.5 in the text illustrates this relationship .

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Biomolecules. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
