The bicarbonate buffering system in the blood is the most important buffering system in the ECF. Bicarbonate ion and carbonic acid are the key components of this buffering system. The weak base <u>bicarbonate</u> serves to buffer the strong acid <u>H+</u><u>.</u> The buffer to the strong base <u>OH-</u><u> </u>is <u>carbonic acid</u>. The byproduct of these reactions is <u>water.</u>
Explanation:
A buffer system utilizes chemical buffers and resists any changes in the pH and adjusts acidity and alkalinity of the medium by binding or releasing H+ ions accordingly.
A bicarbonate buffering system in the ECF regulates the bicarbonate level and maintains the normal acidity level of blood.
Sodium bicarbonate reacting with a strong acid (HCl) produces a weak acid (carbonic acid) and sodium chloride. A strong base like (NaOH) reacts with carbonic acid producing bicarbonate and water.
NaHCo3 + HCl → H2CO3 + NaCl
H2Co3 + NaOH → HCO3 + H20
The acidity of the blood is regulated by maintaining the ratio of bicarbonate and carbonic acid at 20:1 under normal conditions through the bicarbonate buffer system. The carbonic acid level is regulated by the respiratory system; while carbonate level is regulated by the renal system.

➷ It would be D. 25 degrees. This is because there was the highest oxygen flow at this temperature meaning that the rate of photosynthesis was higher.
