Question

When the velocity of enzyme activity is plotted against substrate concentration, which of the following is obtained?

• A. \( \text{Parabola} \)
• B. \( \text{Hyperbolic Curve} \)
• C. \( \text{Straight line with positive slope} \)
• D. \( \text{Straight line with negative slope} \)

Hint:

The hyperbolic curve in enzyme kinetics reflects saturation, where adding more substrate does not increase velocity.

Answer 1

The Correct Option is B

The Michaelis-Menten plot describes enzyme kinetics, where velocity (\( V \)) versus substrate concentration (\( [S] \)) produces a hyperbolic curve. At low substrate levels, the reaction is first-order, increasing proportionally to \( [S] \), but at high substrate levels, the enzyme becomes saturated. This results in a plateau effect, where \( V_{\max} \) is reached.
