Strand 2: Structures & Processes

Metabolism & Enzymes

Enzymes as biological catalysts, the induced fit model, factors affecting enzyme activity, and industrial applications of enzymes.

Enzyme Activity Lab

Adjust temperature and pH to see how they affect reaction rate.

Reaction rate

100%

Optimal activity

Enzymes have an optimum temperature and pH. Below the optimum, molecules collide less often. Above it, the active site changes shape (denatures) and the substrate no longer fits.
