Enzymes and Their Properties

*Note: THIS IS A STUDY GUIDE!! I did non write it to be considered as an essay, rather to assist every confused Bio students, help out with homework, or any variant purpose that people see fit. Please do not critique my format, its not an essay! Enzymes be proteins that acts as catalysts in organisms. A catalyst is a substance that speeds up replys without the gain of heat; decreases the activation energy needed for the answer to standoff on place by bringing molecules in brush up with sepa esteemly other, no longer relying on chance collisions. well-nigh enzymes residuum in ase. The alive(p) site of the enzyme is the part that comes in refer with the substrate, which is the molecule acted on by the enzyme. There ar 2 models that show how they work: -Lock and Key Model-active site only allows undeniable molecules to fit in, molecule separates and leaves, enzyme is unchanged and can be reused. -Induced number Molecule- the active site is not rigid, changes as substrate enters.

Properties of Enzymes- A single enzyme molecule can catalyze thousands of substrate chemical reactions per second, apiece enzyme only kit and caboodle on one type of reaction, enzymes are not changed or used up in a reaction, enzyme does not determine direction of reaction, lower temperature= rate of reaction will be reduced, senior high schooler=enzyme= more(prenominal) effective, as well as high=denaturization (enzyme begins to break down, changes shape to stop functioning. ) Optimum tempe rature= 25-40 C. Enzyme works silk hat at a! certain pH (7). rank of reaction depends on concentration of enzyme and substrate, temperature, and pH. However, at high substrate concentrations, the rate will not increase further upon adding more substrate, which is cognise as saturability. Coenzymes- organic cofactors, some vitamins. Irreversible Inhibitors- bail to active site and permanently cripple the enzyme. Competitive Inhibitors- substances that obstruct an...
