Quizplus · Accepted Answer

Chemical substances in body fluids that prevent rapid changes in pH are called buffers. Buffers are able to resist changes in pH by either accepting or donating hydrogen ions (H+). This helps to maintain the pH at a relatively constant level, which is important for many biochemical processes in the body. Cofactors, enzymes, coenzymes, and free radicals do not play a direct role in regulating pH.
