Electron Transport Chain. Molecules which carry electrons between photosystems, to build the hydrogen ion gradient to make ATP.
The reaction that removes hydrogen ions from the blood is called the bicarbonate buffering system. In this system, carbonic acid (H2CO3) can bind with hydrogen ions to form bicarbonate ions (HCO3-) and water, effectively removing excess hydrogen ions from the blood.
Compounds like bases (e.g. hydroxides, carbonates) and acidic ions (e.g. acetate, bicarbonate) can bind hydrogen ions (H+) in water by accepting or donating H+ ions through chemical reactions. These reactions either decrease or increase the concentration of H+ ions in solution, influencing the pH level.
Compounds that form ions binding hydrogen ions into water include acids and bases. Acids release hydrogen ions (H+) into water, forming hydronium ions (H3O+), while bases accept hydrogen ions to form hydroxide ions (OH-). These interactions are integral to the concept of pH and acid-base chemistry.
Cells often use an electron transport chain to separate electrons from hydrogen protons. The hydrogen protons are then used during chemiosmosis. A hydrogen ion gradient is formed and the hydrogen ions flow through the ATP synthetase molecule to the other side of the membrane. Hydrogen ions accumulate outside the inner mitochondrial membrane during cell respiration and in the inner membrane space of the thylakoid membrane of chloroplasts during photosynthesis. Bacteria use the outside plasma membrane as the surface to build up the hydrogen ion gradient. Therefore the energy from food is transferred to hydrogen ions, and the hydrogen ions transfer the energy to ATP via the ATP synthetase enzyme. In this discussion you should include a discussion of the solar powered purple proton pump and the information found in Figures 6-10, 6-11, 6-12, 6-A, and 8-12 (p. 169). Chemiosmosis is critical in ATP production in eukaryote cells as well as most prokaryote cells.
The largest source of excess hydrogen ions in the body is typically the breakdown of carbohydrates, proteins, and fats during cellular metabolism. This process produces acidic byproducts that release hydrogen ions into the bloodstream. Additionally, conditions such as kidney dysfunction or respiratory issues can also result in an accumulation of hydrogen ions.
Yes, carbonic acid can act as a buffer in the body by binding excess hydrogen ions to help regulate pH. It can form bicarbonate ions, which can then release hydrogen ions if pH levels become too high.

The thylakoid
chemiosmosis is the method of ATP production in living organisms due to movement of hydrogen ions via proton protein pumps in a membrane. It involves the use of the enzyme ATP synthetase
Hydrogen ions (H+) split into protons (H+) and electrons (e-) during chemical reactions.

The phosphate buffer system consists of two ions: dihydrogen phosphate ions and hydrogen phosphate ions. When the number of hydrogen ions in a body's bloodstream increases (pH drops), hydrogen phosphate ions accept hydrogen ions in order to maintain the equilibrium between the concentration of hydrogen and hydroxide ions within the bloodstream. When the number of hydrogen ions in the bloodstream decreases (pH increases), the resulting dihydrogen phosphate ions release hydrogen ions in order to increase the number of hydrogen ions in the blood.
The hydrogen ions for the photosystems of the light-dependent reactions originate from water molecules during the process of photosynthesis.
