Question

Which one of the following best describes the interaction of an enzyme and its substrate?

• A. Fluid-mosaic model
• B. Induced-fit model
• C. Oparin hypothesis
• D. Lyon hypothesis
• E. Competitive-exclusion principle

Answer 1

The correct option is B Induced-fit model

Lyon hypothesis of the Fluid-mosaic model describes ultrastructure of lipid bilayer while oparin hypothesis is about conditioning reflexes. Lyon hypothesis describes the presence of Barr body while competitive exclusion principle tells about overlapping of ecological niche. Induced-fit model describes induced changes in active site of the enzyme by binding of substrate. Thus, the correct answer is B.
