MDCAT Biology MCQ #3290

  1. Question 1

    Q1. Emil Fischer proposed a model in 1894 where the enzyme and substrate have rigid, complementary shapes. This model is:

    • A) Lock and key model
    • B) Induced fit model
    • C) Allosteric model
    • D) Cooperative model

    Answer: Lock and key model

    Explanation: The lock and key model emphasizes rigid complementarity; the induced fit model is more accurate as it accounts for conformational changes.
