  1. Question 1

    Q1. Emil Fischer proposed a mechanism where the enzyme's active site has a specific, rigid geometric shape that exactly matches the substrate. Name this model.

    • A) Induced Fit Model
    • B) Lock and Key Model
    • C) Fluid Mosaic Model
    • D) Feedback Inhibition Model

    Answer: Lock and Key Model

    Explanation: The Lock and Key model assumes a rigid active site. The Induced Fit model suggests the active site is flexible and changes shape.
