BIOL 201 Study Guide - Final Guide: Atp Synthase, Oxidoreductase, Enzyme Commission Number
Document Summary
Part of a molecule is cleaved and transferred to h2o. Functional group is transferred from a molecule to another. May be indicated by a bad leaving group. Nothing lost; no hydrolysis or oxidation; no atp. Hydrolase: catalyzes the cleavage of a molecule by transferring part of it to h2o. Oxidoreductase: catalyzes an oxidation-reduction reaction between two molecules. A dehydrogenase catalyzes a redox reaction involving 2e- and 1 or 2 h+ between 2 molecules, one of which is nad(p)h/nad(p)+ Transferase: catalyzes the transfer of chemical groups between molecules. A kinase catalyzes the transfer of a phosphoryl (phosphate) group between two molecules, one of which is atp. Ligase: catalyzes the joining of 2 molecules in a reaction requiring atp. Synthase: catalyzes the joining of 2 molecules to make 1 molecule without atp involvement. Lyases: catalyze the splitting of 1 molecule into 2 molecules opposite of synthases. Synthases are the hardest enzymes to recognize for the following reasons:
