Answer:CHANGE (the rate of reaction will reduce since living cells exist in medium level PH)
Explanation:
PH is a term used to describe the degree of acidity or alkalinity of a solution,or a medium. PH is a major determining factor in the study of the rate of chemical reactions. When the PH is altered,the rate of reaction taking place will eventually change according to the requirements of the catalysts of the reaction.
In living organisms most of the catalytic functions of enzymes are PH dependent. Different enzymes require different PH level for optimal performance.
