2.4.1 - Enzymes: Biological Catalysts:

Active Site: Tertiary structure on surface, complementary shape

Catalyst: Increase reaction rate, unchanged, reuseable.

Extracellular: Outside cell.

Intracellular: Inside cell.

Metabolism: Chemical reactions in living organisms.

Product: Made in reaction between substrate and enzyme.

Substrate: Altered by enzyme catalysed reaction.

Enzymes catalyse reactions at low temps, neutral pH, normal pressure. They are more specific (no waste). Cells regulate activity/production.

Structure determines function. Instructions for enzymes in genes, mutations alter amino sequence/shape and stop it from working.

Active site, tertiary structure specific to certain subs. Increasing temp/changing pH will affect bonds/shape (denature).
