Acid based write-up Introduction: The pH of blood plasma needs to be regulated. This is because enzymes are present in the blood. Enzymes are globular proteins and are sensitive to pH. A significant change in pH would cause the enzymes to denature and enzymic reactions would cease. The pH of blood plasma is in the region of 7.4, while the pH within the cells is much lower then in the plasma, of the order of pH 6.1. This is because the H+ is made within the cells and this means a high concentration of H+, hence a lower pH (more acidic pH). Hydrogen ions in the blood plasma are dependent on two components: 1). The respiratory component and 2). The metabolic component. The respiratory component is the amount of CO2 present in the plasma. The metabolic component is the organic acids e.g. lactic acid and ketone bodies present. The CO2 factor is...
