Biology- Maintaining a Balance

1. Most organisms ar progressive in a special(a) temperature picture Identify the role of enzymes in metabolism, describe their chemic pick of music and use a precise sit checkmate to describe their specificity on subst appraises Molecules: Consist of atoms Enzymes: Break the molecule bonds, except need vitality to do so ACTIVATION zip fastener (required to start chemical reaction) 1. The role of enzymes in metabolism 1. metabolic process refers to entirely 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 vigor 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 aminic group Acids 7. When e nzymes denature 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 substratums 9. The Chemical on which an enzyme acts is called a substrate 10. The active site of the enzyme fits the substrate handle a lock and account 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 active site of the en zyme like a key fits a lock. Assumes the enz! yme has a rigid and unchanging shape substratum Bonds In Substrate argon Weakened PRODUCTS mobile range 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 clean shape of the enzyme better...If you want to get a full essay, rely it on our website: BestEssayCheap.com
