What is mean by Enzymes ?

Enzymes are special proteins in living organisms that speed up chemical reactions inside the body.

Role of Enzymes:
You can think of them like biological helpers that make reactions happen quickly and smoothly without being used up themselves. In our body, many chemical reactions are happening all the time, like digestion of food, building new cells, and releasing energy. These reactions would happen very slowly without enzymes, or sometimes not happen at all in a useful time.

How Enzymes Work:
Enzymes solve this problem by lowering the energy needed for reactions to start, so everything works fast enough to keep us alive.

Specific Nature of Enzymes:
Each enzyme has a specific job, just like a key fits only one lock. For example, some enzymes help break down food in your stomach, while others help in making energy inside cells. Because of this specificity, every enzyme works only with a particular substance or reaction.

So in simple words, enzymes are natural protein helpers in the body that speed up life processes and make all biological reactions possible at the right speed.
