Students are required to know the following;
Students should be able to relate knowledge of enzymes to metabolism.
Students should be able to carry out rate calculations for chemical reactions.
Enzymes catalyse specific reactions in living organisms due to the shape of their active site.
Students should be able to use the ‘lock and key theory’ as a simplified model to explain enzyme action.
Students should be able to explain the importance of sugars, amino acids, fatty acids, and glycerol in the synthesis and breakdown of carbohydrates, proteins, and lipids.
Metabolism is the sum of all the reactions in a cell or the body.
The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules.
