- Shape and fit
- enzymes have a specifically shaped active site
- complementary to the shape of the SUBSTRATE or molecule
- substrates that are much smaller than the active site of an enzyme can fit
- LOCK AND KEY THEORY
- The substrate 'key' fits into the active site 'lock'

- INDUCED FIT HYPOTHESIS
- charges in the amino acids in the active site contribute to holding the substrate
- substrate molecule COLLIDES with an enzyme's active site- changing the shape of the enzyme slightly
