how much energy is required to pump proton against pH 2?
Describe how a proton pump transforms energy, and how the transformed energy is utilized by membrane transport proteins.
V-type proton ATPase (proton pump): a: What type of transport is a V-type proton ATPase (an integral membrane protein) uses ATP directly to transport protons across the membrane ? (PRIMARY OR SECONDARY) b: With the understanding of sodium-potassium pump, describe how a proton pump would use ATP to move protons against their concentration gradient (out of the cell) ? please do not say energy.

The osteoclast proton pump acidifies the outside of the cell to pH3 from a pH value inside the cell of 7. The potential across the osteoclast plasma membrane is 60mV (inside more negative). Given intracellular concentrations of ADP = 1mM and phosphate = 0.5 mM, what ATP concentration is necessary to drive the transport of two moles of protons outside the cell per mole of ATP hydrolyzed? The temperature is 37°C, and the standard free energy change for ATP hydrolysis...
