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).
How Enzymes work. 1. Enzymes catalyse only those reactions that happen naturally. 2. Enzymes are specific: each enzyme is responsible for only 1 kind of reaction, because they are shaped to work with only a certain substrate that matches enzyme's active site. 3. Enzyme changes its conformation when substrate bonds to its active site.
