Biology enzymes coursework prediction: i think that the enzyme will work best at 45c to 50c i think this because that optimum temperature for most natural enzymes is 40c but his is a chemical enzyme so it will work best a little higher. Enzymes need to collide with their respective substrates in order to generate a reaction, increasing the temperature will give the enzymes and their substrates more energy, increasing the likelihood of collisions to occur, and successful collisions to happen, ultimately increasing the rate of respiration.
Enzyme controlled reactions proceed 10 8 to 10 11 times faster than corresponding non-enzymic reactions substrate the substrate of an enzyme are the reactants that are activated by the enzyme.
