What are the key points in the lock and key model?
A single molecule or more has a complementary shape that can fit into the active site. Temporary bond are formed with the amino acids of the active site to produce an enzyme substrate complex. The enzyme is left unchanged.

What are the key points of the induced fit theory?
The active site is flexible. The specifically shaped substrate will induce the correct change in shape of an enzyme's active site. The slight change in shape enables the substrate to react.

What are enzymes?
Biological catalysts that reduce activation energy.
4 of 6
What is the activation energy?
The minimum amount of energy required to break bonds in order to start a reaction.
5 of 6
How do enzymes reduce the activation energy?
The enzyme's active site and the complementary substrate consist of electrically charged groups. The attraction of the oppositely charge groups distort the shape of the substrate and assists in the breaking of the bonds.
