A protein with catalytic properties due to its power of specific activation. Repro. Enzyme question. Slides 17-22. Specification. Starter. Jot down the key ideas from last lesson on to some scrap/spare paper.. What were some of the key words and phrases?. Use them in a sentence/paragraph to describe what enzymes do.... Anabolism vs Catabolism. What is necessary for a chemical reaction to begin?. Reactant(s) must come together in the right orientation. With enough energy. So ho do enzymes catalyze this process?. Lowers activation energy. ATP. ATP powers cellular work by coupling exergonic and endergonic reactions. ATP Drives:. Mechanical work like the beating of cilia, muscle contraction, cytoplasmic flow, chromosomal movement. Transport work like pumping substances across membranes. . . Here we make use of an integrated approach using high-magnetic-field solid-state NMR, X-ray crystallography, and first-principles computation that enables the investigation of enzyme catalysis at a fine level of chemical detail. The X-ray crystal structure provides a coarse framework upon which models of the active site are built using first-principles computational chemistry and various active site chemistries are explored. . National . 5 Revision. Think!. In your jotter make a quick mind map of all learning points on . enzymes. you can remember from National 5.. Now take a look at the mind map made by someone sitting next to you – can anything be added to yours?.
