Enzymes are proteins that catalyze (i.e. accelerate) chemical reactions.[1] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products. Almost all processes in a biological cell need enzymes in order to occur at significant rates. Since enzymes are extremely selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
so to put it easier, they are proteins that break down food, or other molecules. good luck.

Enzymes are essentially like tools of the body. They are used primarily for jobs dealing with breaking things down or horomones.
They are made up of amino acids that are assembled in cells in ribosomes by instruction of the nucleus.
Many common functions of enzymes are breaking down the starch in the food you eat, or breaking down toxins in the liver.
Each enzyme has one specific job that it preforms in the body at high speed.

Enzymes are complex protein molecules produced by living organisms.they bring about changes & speed up chemical reactionsbut they are not themselves changed at the end of the reaction.sometimes they are called biological catalysts.
Enzymes are:
*proteins *specific *sensitive to pH
*sensitive to temperature
*catalysta that speed up chemical reactions
and remain unchanged at the end of the
reaction.
