Which of the following IS NOT a functional group which can be associated with sugars. The subcellular membrane has no attached ribosomes, has enzymes which synthesize phospholipids and other enzymes which detoxify poisons. Shown to the right is an image which you have seen in class. Enzymes increase the energy which is available, thus increasing the possibility that reactants will reach the transition state and thus complete the reaction. Enzymes interact the reactants and the products providing a different transition state which has a lower activation energy.
Enzymes provide the activation energy to make the reactions proceed.
