The proton pump see concept 36.2 (page 786) the proton pump see concept 36.2 (page 786) uses the energy stored in atp to produce a hydrogen ion gradient across membranes. uses the energy of a proton gradient to generate atp is a passive process operates by osmosis releases kinetic energy

uses the energy stored in atp to produce a hydrogen ion gradient across membranes

The proton pump is a membrane protein that could actively able to moves H+. This action will need energy since the movement is against the gradient of concentration. Like all other pumps, the energy source would be ATP. Proton pump has a role in acid secretion in human.

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .

You would do 1500/4 and the answer is 375
