Competitive vs Noncompetitive Inhibitors

Description

Enzyme inhibitors are molecules that reduce enzyme activity by binding to enzymes. Cells use these inhibitors to help regulate normal enzyme function. Drugs and toxins can also block enzymes and change how they work.

Some inhibitors bind at the active site, which is the part of the enzyme where t...

特定的化学物质可以通过

抑制和阻碍酶的功能 从而规范它们的行动

酶抑制剂会形成两种不同的形式

竞争性的和非竞争性的

竞争性酶抑制剂

与可以与酶活跃部位结合的

酶的特定底物相似

它可以阻碍底物与酶活性部位的结合

这一行为根本上地减少了

可以与底物结合的酶的数量

相反地 非竞争性酶抑制剂

会结合在酶的活性部位以外 但还是会产生影响

例如 它通过改变酶的形状

以及大量地减少
