Enzymes work by a. increasing the speed of electrons b. lowering the energy needed to break bonds c. adding heat to reactant molecules in solution d. making reactants water-soluble

Enzymes work by reducing the energy of activation increasing the potential energy difference between reactant and product decreasing the potential energy difference between reactant and product adding energy to a reaction reducing EA adding a phosphate group to a reactant
aka B

Reduction in overall biodiversity
