Question

Identify the INCORRECT statement with reference to enzymes.

विकल्प

• Lock and key analogy for enzyme action is proposed by Emil Fischer.

• Induced Fit model for enzyme action is proposed by Koshland.

• Increase in substrate concentration decreases the velocity of enzyme activity.

• Protease is a purely proteinaceous enzyme.

Answer 1

Increase in substrate concentration decreases the velocity of enzyme activity.

Explanation:

An increase in substrate concentration generally increases the rate of enzyme activity until a certain point, called the saturation point, where all enzyme molecules are occupied. This is known as the saturation kinetics of enzyme activity.
