the citric acid cycle is activated in the presence of oxygen (o2), but what is the link between the citric acid cycle and o2?
Citric acid cycle uses free oxygen as the final electron acceptor.O2 is an allosteric activator for citrate synthesis.
The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP. The presence of O2 in mitochondria releases CO2 into cytosol. One molecule of ATP is produced per each turn of the cycle. The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor for electrons removed from the intermediate compounds in glucose catabolism. The electrons are passed through a series of chemical reactions with a small amount of free energy used at three points to transport hydrogen ions across the membrane. This contributes to the gradient used in chemiosmosis. As the electrons are passed from NADH or FADH2 down the electron transport chain, they lose energy. The products of the electron transport chain are water and ATP. A number of intermediate compounds can be diverted into the anabolism of other biochemical molecules. such as nucleic acids, non-essential amino acids, sugars, and lipids. These same molecules except nucleic acids can serve as energy sources for the glucose pathway.

What is the use of the buffer solution ?
A buffer is an aqueous solution made up of a weak acid and its salt (acid buffer) or a weak base and its salt (base buffer) (basic buffer). When a small amount of strong acid or base is added to it, its pH changes very little, and it is thus used to prevent the pH of a solution from changing.
Buffer solutions are utilised in several chemical applications. Blood is one example of a natural buffer solution. The natural pH of human blood is 7.4. Many people suffer from severe anxiety and alkalosis. Alkalosis is a condition in which the blood pH is abnormally high. The opposite situation is known as acidosis, which occurs when the pH of the blood exceeds 7.4.
