Document Summary

Enzyme function is determined by the ph of the environment. Enzymes must remain normal essential for normal metabolic functioning. There is continual production of acids by the various metabolic processes in the body. Obligation to get acids out of bodies. Sulphuric acid is the main non volatile acid. Non- volatile = excreted through the kidneys. Carbon dioxide is the main volatile acid. Co2 + h2o h+ + hco3. When there is more co2 in the body more free protons (more acidic) If environment is alkaline limited free protons. If environment is acidic lots of free protons. The body has three main systems by which ph is controlled. The kidneys control excretion of acid from body = regulate ph. The lungs control excretion of acid from body = regulate ph. The use of buffers a (cid:271)a(cid:272)k up s(cid:455)ste(cid:373) or (cid:858)proto(cid:374) (cid:271)a(cid:374)k(cid:859) protons are still in body but take free protons out of the environment.
