Question

Which of the following graphs depicts the effect of substrate concentration on velocity of enzyme catalysed reaction?

A

Graph showing linear increase indefinitely

B

Graph showing a bell-shaped curve

C

Graph showing velocity increasing to a maximum (Vmax) and then plateauing (Hyperbolic curve)

D

Graph showing velocity decreasing with concentration

Step-by-Step Solution

According to the text, 'With the increase in substrate concentration, the velocity of the enzymatic reaction rises at first. The reaction ultimately reaches a maximum velocity (Vmax) which is not exceeded by any further rise in concentration of the substrate'. This occurs because enzyme molecules become saturated. Figure 9.5(c) 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.
