Question

Quizplus · Accepted Answer

Enzymes are biological catalysts that increase the rate of chemical reactions without being consumed in the process. They do not alter the free energy change of a reaction or change the direction of the reaction. Enzymes are not permanently altered by the reactions they catalyze, as they can be reused. Enzymes also do not prevent changes in substrate concentrations.
