Biology- Maintaining a Balance

1. Most organisms ar progressive in a special(a) temperature prevail Identify the role of enzymes in metabolism, describe their chemic set up of music and use a detail sit consume to describe their specificity on subst prizes Molecules: Consist of atoms Enzymes: Break the molecule bonds, alone need vitality to do so ACTIVATION cipher (required to start chemical reaction) 1. The role of enzymes in metabolism 1. transfiguration refers to all in all the chemical reactions occurring in organisms 2. Enzymes are biological catalysts for all processes going on inner cells. 3. They are able to be used over and over again 4. They increase the rate of chemical reactions at lower temps and pass the activation nix needed for metabolic reactions to occur 2. Chemical write up of enzymes 5. enzymes are made up of proteins 6. i.e. long chains of amino group group Acids 7. When enzymes d enature the cross linkage bonds are broken, protein loses its expression check and becomes inactive 8. The substratum is the molecules which the enzyme acts upon 3. enzyme specificity on substrates 9. The Chemical on which an enzyme acts is called a substrate 10. The active site of the enzyme fits the substrate alike a lock and chance on 11.

They are highly specific in their actions; this means that each enzyme acts on one substrate only 4. Models to explain specificity: 12. The Lock and key model states that the substrate fits exactly into the acti ve site of the enzyme like a key fits a lock! . Assumes the enzyme has a rigid and unchanging shape substratum Bonds In Substrate argon Weakened PRODUCTS brisk come in ENZYME ENZYME-SUBSTRATE ENZYME Substrate Bonds In Substrate Are Weakened PRODUCTS Active Site ENZYME ENZYME-SUBSTRATE ENZYME 1. The induced fit model states that the binding of the substrate to the enzyme induces a temporary change in the shape of the enzyme. The new shape of the enzyme better...If you want to get a full essay, rely it on our website: BestEssayCheap.com
