ENZYMES

Enzymes are proteins specifically shaped to carry out special functions in cells:

• They accelerate the rate of chemical reactions necessary for life.
• They need many enzymes as each specific reaction needs a specific enzyme.
• Any changes in their shape will effectively stop chemical reactions.

Proper protein function depends on correct 3D structure. This is especially important for enzyme activity:

• Enzymes are vital to proper cell function.
• Defects include sickle cell anemia and cystic fibrosis.

Enzymes take a Substrate and convert it into a new Product (see illustration to the right.)
