Enzymes and Metabolism

Enzymes: biological catalysts involved in biological reactions speeding it up without being used up in the reaction itself

They are globular proteins composed of one or more polypeptides

Structure is affected by changes in temperature and pH

The rate of reaction is the amount of product produced per unit of time

Metabolism is the complex network of interdependent and interacting biochemical reactions occurring in living things

Enzymes are specific to their particular substrate

Anabolic reactions are involved with the building of large molecules from smaller ones

Energy (ATP) is required)

Condensation reaction - H2O is released

Catabolic reactions are involved with breaking down large molecules into smaller, simpler ones

Energy is released

Hydrolysis reactions - H2O needed
