Question

which of the following factors might influence cellular respiration?
temperature
acid addition
water intake
water density

Explanation:

Cellular respiration is an enzyme - mediated process. Temperature affects enzyme activity. Acid addition can change the pH which also impacts enzyme function. Water intake can influence the availability of reactants and the cell's internal environment for respiration. Water density has no direct impact on the biochemical reactions of cellular respiration.

Answer:

temperature, acid addition, water intake
