Study Notes
Enzymes
- Catalysts increase reaction rate but don't affect equilibrium or spontaneity
- Enzymes are biological catalysts, often proteins
- Enzymes have active sites that bind specific substrates, increasing reaction speed
- Active sites exhibit induced fit—they change shape to accommodate substrates
- Ribozymes are non-protein enzymes, made of RNA
- Cofactors are molecules that bind enzymes and help them function
- Holoenzyme: enzyme bound to its cofactor
- Apoenzyme: enzyme without a cofactor
- Enzymes catalyze reactions in diverse ways, including substrate proximity, acid/base, and electrostatic interactions
- Phosphatases remove phosphate groups from substrates
- Phosphorylases add phosphates to substrates
- Kinases transfer phosphates from ATP to substrates.
