Cellular respiration involves a series of chemical reactions. which of the following is a primary way that enzymes affect these reactions?
a. they decrease the ph of the products.
b. they increase the rate of the reactions.
c. they take the place of oxygen as a reactant.
d. they change the location of the reactions in the cell.

Cellular respiration involves a series of chemical reactions. The enzymes increase the rate of the reactions. So option “B” is the correct option as far as the given question is concerned. The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.
