The concept of “induced fit” refers to the fact that _______ |
| A. | When a substrate binds to an enzyme, the enzyme induces a loss of water (desolvation) from the substrate |
| B. | Substrate binding may induce a conformational change in the enzyme, which then brings catalytic groups into proper orientation |
