What are enzymesenzymes are biological catalysts they speed up chemical reactions in all living things, and allow them to occur more easilythey occur in plant cells and animal cells without them we would not be alive although they work powerfully, enzymes are just chemical molecules, made up of proteins they are. Class practical or demonstration hydrogen peroxide (h2o2) is a by-product of respiration and is made in all living cells hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell cells make the enzyme catalase to remove hydrogen peroxide. Notwithstanding these notable exceptions, much of classical enzymology, and the remainder of this essay, is focused on the proteins that possess catalytic activity advances in molecular biology enable us to purify recombinant proteins, including enzymes, through affinity tagging in a typical approach. Standards: biology/life sciences - cell biology b students know enzymes are proteins that catalyze biochemical reactions without altering the reaction equilibrium and the activities of enzymes depend on the temperature, ionic conditions, and the ph of the surroundings procedure: understand the enzyme catalase.

Paul andersen starts with a brief description of enzymes and substrates he then explains how you can measure the rate of an enzyme mediated reaction catalase from yeast is used to break hydrogen peroxide down into water and oxygen he also explains how temperature and ph could affect the rate of.
