__ HOW DOES CHEMICALS IN HUMAN BLOOD MAINTAIN THE BLOOD PH LEVEL OF 7.2 AND 7.4? __ **Namkyu Kaang **



__ **What is the chemical in human blood that helps maintain a blood pH? ** __ chemoreceptor from the medulla oblongata detect the change in concentration of CO2. T hose chemoreceptor then sends signal to intercostals muscles and diaphragm to control the breathing rate and to make the blood pH level constant

__ **Why should the blood ph level be kept constant? ** __ If the blood becomes too acidic, then it is difficult for carbon dioxide to enter the bloodstream from the cells. This may cause a condition called acidosis. On the other hand, if the blood becomes basic then it will cause alkalosis which there is excessive base in the body fluids.

__ **How does it work? ** __ The balance is maintained by buffers in the blood such as indeed bicarbonate, and also ammonia. The next system is the respiratory system. Any decrease in pH is detected by chemoreceptor and stimulates a faster rate of ventilation. This results in a more carbon dioxide being blown off, which raises the blood pH back towards normal. And vice-versa. The final system, which is the slowest mechanism but also has the most capacity for regulation of pH is the kidneys' ability to excrete excess acid or base

__**Why is the blood ph level so important? **__ Enzymes are pH sensitive and changes in pH will cause ion bonds to form/break causing a change to the 3D teriary structure of the protein. Therefore the enzymes will denature and no longer be complementary to the substrate if the pH level is not constant.
