Weba) A given enzyme catalyses just one type of reaction b) While most enzymes are proteins, some are composed of RNA c) The activity of enzymes is typically impaired at high temperatures d) Enzymes act to lower the activation energy of a reaction by stabilising the transition state, but do not participate chemically in the reaction Question 9 WebThe activation energy of a chemical reaction is kind of like that “hump” you have to get over to get yourself out of bed. Even energy-releasing (exergonic) reactions require some amount of energy input to get going, before they can proceed with their energy-releasing steps. This initial energy input, which is later paid back as the reaction ...
