Describe that lock and key hypothesis

Enzymes are biological catalysts, which means that they increase the rate of a specific reaction by lowing the required activation energy.
The lock and key hypothesis explains how the substrate (key) fits into the active site of the enzyme (lock). The substrate is complementary in shape to the active site and so only the correct substrate can fit; much like a key can only fit in one lock
