Question 12 Which of the following are true about the properties of enzymes? (select all that apply) They are sensitive to environmental factors such as temperature and pH. They increase the rate of a reaction by shifting its equilibrium point. They increase the rate of a reaction by making it more exergonic. ✔They increase the rate of a reaction by lowering the activation energy. Enzymes increase the rate of a reaction by completely blocking the reverse reaction.
