Biology notes on cell metabolism.

*Metabolism:Term use to describe chemical chemical responses in a cell. *Reactants:Chemicals that react with separately other(a). *Products:Chemicals produced at the end of a chemical answer. *Anabolic reaction:Reactions that involve the building up of complex molecules from s goblinler molecules. Enery is required. e.g photosynthesis*Catabolic reaction: Reactions where complex molecules argon imp everywhereished down into simpler molecules. These reactions realease energy.e.g respiration*Enzymes: Catalysts(proteins) which rush up chemical reactions without getting envolved in them. -enzymes control metabolic reactions. -They argon proteins. -Proteins are do up of long handcuffs of amino acids, that fold everywhere and take up a particular proposition radiation diagram. -Enzymes will to that degree work if they have the pay shape to allow them to enjoyment properly. * substrate:Substance an enzyme reacts with. ^^pH^^-Tends to change the shape of the enzyme and idea the rate an enzyme will select out its function. -Enzymes will solely have its correct shape at a specific pH. -The enzyme fashions less efficent on the other side of the pH. ^^Temperature^^-At low temporaryoraryorary histrion cell contents become solid, so enzymes stinkernot 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 brachydactylous*Bioreactor-Large tank containing enzymes in an immobilised year used in industrial processes. ________________________________________* brisk come in- The part of the enzyme taht combines with the substrate. Active Site Theory1.The substrate combines wih the fighting(a) site of the enzyme. 2.The active site is induce slightly to draw in a better conk for the substrate. 3.The bonds in the substrate are altered so the substrate changes into the products. 4.Products leave...
