- enzymes
- they are globular, which acts as a catalyst by lowering the activation energy
- they control virtually all metabolic reactions in and out of cells
- each enzyme has its own substrate
- this is because there has to be a perfect match between the active site and substrate
- in order for the enzyme substrate complex to form
- usually binding with the substrate will cause a change in the enzymes shape, allowing it to compliment the substrate perfectly
- this is called induced fit
- this is because there has to be a perfect match between the active site and substrate
- Untitled
- anything that affects the active site, i.e temperature or change in ph will cause a reduction in activity and denaturing of the enzyme
- inhibitors
- competitive inhibition
- this is when the inhibitor competes with the substrate for a position in the active site
- concentration levels can mean if the inhibitor works or not
- this is when the inhibitor competes with the substrate for a position in the active site
- non-competitve inhibitors
- these bind to an alosteric site that alters the active site so it can't form the esc
- can be reversible or irreversible depending on the timings
- competitive inhibition
- they are globular, which acts as a catalyst by lowering the activation energy
