What compounds form ions that bind hydrogen ions in water?
Base
What is chemiosmosis and how does it work?
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.
What ions accumulate in the outer compartment of the mitochondria during electron transport phosphorylation?
Hydrogen ions
Acids are compounds that dissociate in water and release what?
Acids release hydrogen+ ions (H+) when dissolved in water

Can carbonic acid bind excess hydrogen ions to raise Ph?
No. Carbonic Acid releases hydrogen ins and lowers pH. Carbonates and bicarbonates, which can be derived from it, do bind hydrogen ions and lower pH.

What accepts hydrogen ions?
It is a Base
What ions accumulate in the outer compartment of the mitochondria during electron transport phosphorylation?
Hydrogen ions
What is the product of chemiosmoisis?
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
Do bases release or accept hydrogen ions?
Bases accept hydrogen ions. Acids donate hydrogen ions.
Where do hydrogen pumps move hydrogen ions in what structure?
They move hydrogen ions in the thylakoid.
How does the phosphate buffer system help in maintaining the pH of our body?
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.
Acids are compounds that dissociate in water and release what?
Acids release hydrogen+ ions (H+) when dissolved in water
Do acidic solutions give some or many hydrogen ions?
The more acidic a solution is, the more hydrogen ions it gives off.
