Enzyme’s catalytic rate

What is(are) true about the enzymes? (check all that apply) Both enzyme and substrate concentrations affect enzyme’s catalytic rate. All of these Enzyme lowers reaction rates. Enzymes can be reused. Enzyme lowers activation energy.$$A+B\rightleftharpoons C+D$$is a near equilibrium reaction that obeys the Law of Mass Action. How wi this reaction be altered if an excess of$$C$$is added?

It will drive the reaction forward (toward$$C+D$$). It will produce more of the compound$$D$$. It will simply produce more of the compound$$C$$. The equation will not be altered. It will drive the reaction in the reverse (toward$$A+B$$).
