Question

question 1 the induced fit model of enzyme catalysis states that answer the active site of the enzyme changes shape before substrate binds to it the active site of the enzyme changes amino - acid composition after substrate binds to it the active site of the enzyme changes amino - acid composition before substrate binds to it the active site of the enzyme changes shape after substrate binds to it i dont know yet

Explanation:

The induced - fit model posits that the active site of an enzyme is not rigid. When the substrate binds to the enzyme, the active - site undergoes a conformational change (shape change) to better fit the substrate. It does not change the amino - acid composition either before or after substrate binding.

Answer:

the active site of the enzyme changes shape after substrate binds to it
