PPT-Application of Enzymes in Industry

By Manisha A Dhotre Why use enzyme for industrial process 1 Lactase is used in a chlorinefree denim bleaching process which also enables a new fashion look 2 Fructosyltransferase. Understanding:. Enzymes have an active site to which specific substrates bind. Enzyme catalysis involves molecular motion and the collision of substrates with the active site. Temperature, pH and substrate concentration affect the rate of activity of enzymes. Reactions. Most reactions take place in a number of steps which need to be carefully controlled if the cell is to function properly. Enzymes are the most important controllers of cellular reactions. Catalysts. Enzymes as Catalysts. Enzymes are used to speed up chemical (metabolic) reactions e.g. respiration or photosynthesis- so why use enzymes in industry?. They are specific. can catalyse reactions between specific chemicals, even in a large mixture . Warm up. Grab warm up and complete. We will be putting this into your . journal.
