Which process in the light-dependent reactions results in the release of hydrogen ions, electrons, and oxygen?

A) chemiosmosis

B) photophosphorylation

C) water splitting

D) electron transport

The high-energy electron travels down an electron transport chain, losing energy as it goes.

Some of the released energy drives pumping of / text H^ + H + H, start superscript, plus, end superscript ions from the stroma into the thylakoid interior, building a gradient.

H^ + H + H, start superscript, plus, end superscript ions from the splitting of water also add to the gradient.

H^ + H + H, start superscript, plus, end superscript ions flow down their gradient and into the stroma, they pass through ATP synthase, driving ATP production in a process known as chemiosmosis.
