Biology Notes On Cell Metabolism Essay

437 words - 2 pages

*Metabolism:Term used to describe chemical reactions in a cell.*Reactants:Chemicals that react with each other.*Products:Chemicals produced at the end of a chemical reaction.*Anabolic reaction:Reactions that involve the building up of complex molecules from simpler molecules. Enery is required. e.g photosynthesis*Catabolic reaction: Reactions where complex molecules are broken down into simpler molecules. These reactions realease energy.e.g respiration*Enzymes: Catalysts(proteins) which speed up chemical reactions without getting envolved in them.-enzymes control ...view middle of the document...

-Enzymes will only have its correct shape at a specific pH.-The enzyme becomes less efficent on the other side of the pH.^^Temperature^^-At low temp cell contents become solid, so enzymes cannot work.-As temp increases so does rate of reaction because the substrate and enzyme get more energy.-The temp that an enzyme works beast at is its optimum temp.-above optimum temp enzymes denature and rate of reaction drops.__________________________________*Immobilised Enzymes: Enzymes that are attached to eachother or an inert material.Advantages of immobilised enzymes-Can recover enzymes easily- Enzymes can be reused-effiency of enzymes is not affected*Bioreactor-Large tank containing enzymes in an immobilised form used in industrial processes.________________________________________*Active site- The part of the enzyme taht combines with the substrate.Active Site Theory1.The substrate combines wih the active site of the enzyme.2.The active site is induced slightly to make a better fit for the substrate.3.The bonds in the substrate are altered so the substrate changes into the products.4.Products leave active site, active site returns to its original shape and can no except a new substrate molecule.*Denaturation:Change in shape and loss in biological activity in a n enzyme.Bibliographies: New Senior Biology(folens)www.skoool.ie
