In the production of ATP in photosynthesis, energy from electron flow is used to transport from the to the thylakoid compartment, generating a concentration gradient of .

Explanation:

ATP is produced in the process of photosynthesis occurs in plants and many other organisms. Electron are transported  by electron transport chain and there is the generation of concentration gradient of H+.

This gradient causes the activation of ATPase pump which causes the production of ATP by using this gradient.

In the production of ATP in photosynthesis, energy from electron flow is used to transport H+ from the stroma to the thylakoid compartment, generating a concentration gradient of H+.

before it leaves the nucleus of a eukaryotic cell, mrna is altered in the following ways: - a cap is added to the 5' end of the mrna molecule; - a poly a tail is added to the 3' end; - introns are removed and exons are spliced together.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
