Maintaining a Balance Notes

Maintaining A Balance 1.1 Identify the role of enzymes in transfiguration; 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 drive on up reactions so that the body can function properly. For modelling; the enzyme catalase catalyses henry peroxide, producing hydrogen and oxygen. 1.2.2 Describe the chemical composition of enzymes; Enzymes atomic number 18 do up of proteins, which contain carbon, hydrogen, oxygen and nitrogen (CHON). Proteins atomic number 18 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 forget fit into this enzyme . Substrate Substrate Enzyme Enzyme bustling site nimble 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 armed forces action of named enzymes; * Increased temperature * tack in pH * Change in substrate concentrations 1.3.
