Which of the following is true of enzymes? enzymes may require a nonprotein cofactor or ion for catalysis to take speed up more appreciably than if the enzymes act alone. enzyme function is independent of physical and chemical environmental factors such as ph and temperature. enzyme function is increased if the three-dimensional structure or conformation of an enzyme is altered. enzymes increase the rate of chemical reaction by lowering activation energy barriers.
