Enzyme

what are co-factors
- non protein chemical compound that binds to enzyme and activates it
- inorganic
- tightyly bound to an enzyme and is required for catalysis
what are coenzymes
- chemical compound that binds to enzyme
- "prosthetic group"
- organic
what is a holoenzyme
- a "whole enzyme"
- = apozenyzme + coenzyme
what are the factors that affect enzyme activity
- [substrate]
- [enzyme]
- pH = charge of protein, too extreme may cause denaturing
- temp = ↑ temp = ↑rxn rate, too high may denature protein
- cofactors
- inhibitors
