Maintaining a Balance Notes

Maintaining A Balance 1.1 Identify the role of enzymes in metabolism; account their chemical composition and use a impartial 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 velocity up reactions so that the body can function properly. For employment; the enzyme catalase catalyses henry peroxide, producing hydrogen and oxygen. 1.2.2 Describe the chemical composition of enzymes; Enzymes argon 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 allow for fit into this enzyme. Substrate Substrate En zyme Enzyme bustling site combat-ready 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 legions action of named enzymes; * Increased temperature * salmagundi in pH * Change in substrate concentrations 1.3.4 Describe an experiment you performed to hand over 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 pipages spud solution Acid solution Distilled weewee Hydrogen peroxide Stopwatch Marking pen metre cylinder Alkaline solutions planetary indicator Pipette rule Method 1.
