- Enzymes
- Activity
- Speed up metabolism
- Speed up rate of a chemical reaction
- Speed up rate of a chemical reaction
- Lower energy required for reaction to take place
- Remain unchanged after reaction
- Can carry out same reaction many times
- Remain unchanged after reaction
- Catalyse reactions within or outside cells
- Speed up metabolism
- Factors Affecting
- pH
- Optimum
- Work best
- Higher
- Denatured
- Lower
- Denatured
- Optimum
- Temperature
- Optimum
- Work best
- Higher
- Shape of active site altered
- Denatured
- Shape of active site altered
- Lower
- Work slower
- Optimum
- Inhibitors
- Competitive
- Compete with substrate for active site
- Non-competitive
- Attach to area other than active site
- Shape of active site changed
- Attach to area other than active site
- Substrate molecule no longer fits onto active site
- Shape of active site changed
- Shape of active site changed
- Slow/stop enzyme activity
- Competitive
- Substrate concentration
- Increase
- Increases until a point where it levels off
- All enzyme active sites reacting with substrate
- Enzymes working at fastest rate possible
- All enzyme active sites reacting with substrate
- Increases until a point where it levels off
- Increase
- Enzyme concentration
- Increase
- Increases rate of reaction
- More active sites available
- Increases rate of reaction
- Increase
- Co-enzymes
- Activate enzymes
- Examples
- Vitamins
- Minerals
- pH
- Activity
