Maintaining a Balance Notes

Maintaining A Balance 1.1 Identify the role of enzymes in metabolism; account their chemical composition and use a b argon(a) 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 further up reactions so that the body can function properly. For usage; 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 substratum particle and indicates that this fits with the curve of the enzyme. It suggests that only this substrate structure entrust fit into this enzyme. Substrate Substrate Enzyme Enz yme bustling site officious site 1.2 Identify data sources, plan, choose equipment/resources and perform a first-hand investigation to test the effect of the following on the soldiers action of named enzymes; * Increased temperature * reposition in pH * Change in substrate concentrations 1.3.

4 Describe an experiment you performed to expose the effect of increased temperature on the activity of a named enzyme; In your answer include: a) a list of the equipment used b) a safety precaution needed c) a bit by bit method d) a general description of your results Equipment 5 test tubes spu! d solution Acid solution Distilled water system Hydrogen peroxide Stopwatch Marking pen mensuration cylinder Alkaline solutions planetary indicator Pipette rule Method 1.
