Each enzyme has an optimal temperature and pH that it works best in. If enzyme ABC works best at pH 7, but ABC is in a cell with a pH of 9, will it catalyze more or less reactions?

Less reactions because it does not have the best pH to for that particular enzyme to work in. If it was at pH of 7, ABC would work best and catalyze a lot of reactions, but since the pH is 9 it will not work as efficiently or better so it will catalyze less reactions.
