(practical 3). 2.5.u5 immobilized enzymes are widely used in industry. list industries that use commercially useful enzymes. explain how and why industrial enzymes are often immobilized. 2.5.a1 methods of production of lactose free milk and its advantages. state the source of the lactase enzyme used in food processing.
2 5 Enzymes Biology4ibdp The role of lactase as it breaks down lactose into galactose and glucose is an application in subtopic 2.5 which students need to know anyway and i love to help my students by double dipping content whenever possible. you can see the slide i use to check in on student progress below, this is usually the day after we have our lesson on enzymes. 2.5 enzymes. an enzyme is a globular protein which acts as a biological catalyst by speeding up the rate of a chemical reaction. enzymes are not changed or consumed by the reactions they catalyse and thus can be reused. enzymes are typically named after the molecules they react with (called the substrate) and end with the suffix ' ase'. Enzyme catalysis. essential idea: enzymes control the metabolism of the cell. u1: enzymes have an active site to which specific substrates bind. u2: enzyme catalysis involves molecular motion and the collision of substrates with the active site. u3: temperature, ph and substrate concentration affect the rate of activity of enzymes. Question. a.)outline the effect of temperature and substrate concentration on the activity of enzymes. [4] b.)distinguish between competitive and non competitive enzyme inhibition of chemical reactions, giving an example of each. [5] c.)explain the light independent reactions of photosynthesis. ️answer explanation.
