Question:
Why are buffers so important to living systems? What are some examples of buffer systems that occur in the human body?



Replies:
Different pH's will cause molecules to gain and loose electrons and protons (ionize). If proteins are not kept at the proper pH they will not function properly by assuming nonfunctional shapes because of changing ionic states. pH is probably the most important single thing the body regulates since it will affect so many others. Proteins are a major buffer; sodium bicarbonate and phosphate are others.
