Thank you.

Part 3.

problems : the inhibitors on the reactivity of enzymes

keywords :

1. competitive inhibitors

similar shape

active site

compete for occupation

rate of reaction

2. Non-competitive inhibitors

not chemically similar

allosteric site

change the shape of the active site

Inhibition is not overcome simply by increasing substrate concentration.
