Within the National 5 Biology course, you will need to know:
- The variety of protein shapes and functions arises from the sequence of amino acids.
- Proteins have many functions such as structural, enzymes, hormones, antibodies and receptors.
- Enzymes function as biological catalysts and are made by all living cells. They speed up cellular reactions and are unchanged in the process.
- The shape of the active site of an enzyme molecule is complementary to its specific substrate(s).
- Enzyme action results in product(s).
- Enzymes can be involved in degradation and synthesis reactions. Examples should relate enzymes to their specific substrate(s) and product(s).
- Each enzyme is most active in its optimum conditions.
- Enzymes and other proteins can be affected by temperature and pH.
- Enzymes can be denatured, resulting in a change in their shape which will affect the rate of reaction.
