Ciclo catalítico de una enzima
1. Substrates enter the active site; the enzyme changes shape so its active site embraces the substrates (induced fit)
2. Substrates held in the active site by weak interactions, such as hydrogen bonds and ionic bonds
3. Active site (and R groups of its amino acids) can lower EA and speed up a reaction by: Acting as a template for substrate orientation, Stressing the substrates and stabilizing the transition state, Provide a favorable microenvironment, Participating directly in the catalytic reaction
4. Substrates are Converted into Products
6. Active site is available for two new substrate molecules
