Yoel Romero looks like he is next for Michael Bisping, while Luke Rockhold and Ronaldo Souza are still waiting in the wings; the Ultimate Fighting Championship does not need another 185-pound power player right now....
In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).
1 They increase the rate of Metabolic reactions. 2  Almost all Biological Reactions involve Enzymes. 3  All enzymes are Globular Proteins with a specific Tertiary Shape. 4  They are usually specific to only one reaction. 5  The part of the Enzyme that acts a Catalyst is called the Active Site. Enzymes work by lowering the Activation Energy of a reaction. 2  The Activation Energy of a reaction is lowered by putting stress on the bonds within a molecule, or by holding molecules close together. 3  This increases the likelihood of a reaction, and so lowers the energy required to begin it.
