The transfer of energy from nutrients to a teepee is accomplished most directly by the process of?

D. At a pH too far from 7.4, enzymes in the blood will stop functioning properly.

Explanation:

The pH of blood is regulated 7.35 and 7.45. pH shows acid-base balance in the body and maintains a healthy balance of acidity and alkalinity.

Balance of acid-base provides optimum condition to enzymes to perform proper function. As, enzymes required optimum pH range for functioning properly, pH too far from 7.4 can denature the enzymes. Enzymes will lose its shape and will not function properly at high pH.

Hence, the correct option is D.
