- energy is provided by ATP, reactants absorbing energy,products high PE
- endergonic
- Energy is stored in ATP molecules, reactants release energy, products low PE-high KE
- exergonic
- minimum amount of energy for chemical reaction to occur
- energy of activation
- Energy coupling
- using exergonic process to drive an endergonic one
- 3 factors influencing enzyme activity
- pH, temperature, salt concentrations
- describe enzyme process
- substrate enters the active site and binds, hydrolysis(adding water) convert the substrate to products, products are released
- competes for substrate place
- competitive inhibitor
- alters the shape of the enzyme
- noncompetitive enzyme
