1.1 Identify the role of enzymes in transfiguration; account their chemical composition and use a simple modeling to describe their specificity on substratums.
1.2.1 Identify the role of enzymes in metabolism; Enzymes catalyse metabolic reactions, both anabolic and catabolic, and speed up reactions so that the body can function properly. For example; the enzyme catalase catalyses henry peroxide, producing hydrogen and oxygen.
1.2.2 Describe the chemical composition of enzymes; Enzymes are do up of proteins, which contain carbon, hydrogen, oxygen and nitrogen (CHON). Proteins are doubled amino acids in different combinations, held together by polypeptide bonds.
1.2.3 tuck away and Key model; Shows the kink of the substrate particle and indicates that this fits with the curve of the enzyme. It suggests that only this substrate structure will fit into this enzyme.

1.2 Identify data sources, plan, choose equipment/resources and perform a first-hand investigation to test the effect of the following on the military action of named enzymes;
* Increased temperature
* Change in pH
* Change in substrate concentrations
1.3.
4 Describe an experiment you performed to show the effect of increased temperature on the activity of a named enzyme; In your answer include:
