Question

Select all of the mechanisms by which enzymes can lower the activation energy of a reaction:

--separating reactants to prevent excess reaction speeds

--bringing molecules together or orienting them in favorable positions

--altering the energy of the products   

--creating a favorable environment (like the exclusion of water around reactants).

--altering the energy of the reactants

Answer 1

mechanisms by which enzymes can lower the activation energy of a reaction

bringing molecules together or orienting them in favorable positions ( enzymes make conformational changes in reactant so that they can easily interact with each other as well as play role as exchange agent to take some electron, cofactors, reactive group etc and donate. )

creating a favorable environment (like the exclusion of water around reactants).

altering the energy of the reactants
