Control METABOLISM  Metabolic reactions can be controlled and sped up by enzymes  metabolic reactions would be too slow to occur if no enzymes were.

 Proteins are composed of smaller units called amino acids.  Amino Acids : Are small compounds that are made of carbon, nitrogen, oxygen, and hydrogen.

Enzymes A quick guide.

Biological catalysts.  Enzymes: proteins inside cells that act as a catalyst.  Proteins = long amino acids chains that are folded into a specific shape.
