According to the induced fit model, what happens when a substrate binds to an enzyme?
Answer and explanation
Correct answer: A. The active site changes shape to fit the substrate and lower the activation energy
- Step 1: Induced fit says the active site is flexible and adjusts around the substrate.
- Step 2: This strains bonds and lowers the activation energy for the reaction.
Answer
the active site changes shape to fit the substrate.
Why not the others: A rigid site describes the older lock and key model; enzymes are not consumed; enzymes do not use ATP to reshape substrates.
