Biology Questions and Answers Essay2.) a) proteinsb.) i) Amylaseii) Proteaseiii) Lipasec) i) Glucoseii) Amino Acidsiii) Fatty acids and Glycerol3.) a.) Each enzyme has a unique(p) shape that fits onto the substrate. As enzymes normally only catalyse one answer the substrate has to fit in the precise shape (active site) and if it doesnt fit in (lock and key method) then the enzyme wont be catalysed. b.) As when the enzyme is denatured its special shape is destroyed, thus destroying its active site message that the substrate wont be able to fit in, therefore not catalysing the enzyme. c.) As enzymes are specific when an enzyme catalyses an enzyme it can be used over and over again as they are not changed during the reaction.5.) a.) if the parsimony of the enzyme is increased the rate f the reaction will increase. This is because there will be more enzymes to uphold break down the substrate, however when the enzyme reaches its optimum it will be equal. b.) if the temperature is decreased it will offload the rate of reaction and slow down the speed of catalysing. c.) if the pH is lowered then the rate of reaction will drop causing the pH to interfere with the bonds holding the enzyme together and denaturing the enzyme.7.) a.) i) the rate of reaction is increase at a positive constant correlation, because the increase in temperature is causing the enzymes to move around hurried increasing the circumstances of a collision. ii) the rate suddenly drops after its hit the optimum temperature, this is because the bonds holding the enzyme together have broke destroying enzymes special shape. b.) It increases it as it causes the enzymes to move around faster increasing the chance of a collision. c.) the bonds change its special shape causing it unable to catalyse substances. d.) A. it could be pepsin in the stomache.) B, it could be phosphatasesf.) it is very narrow.
