During the light reaction, a molecule of water is split apart. explain what happens to each of the following: a. electrons
b. hydrogen ions
c. oxygen atom

Water is split apart through a process called photolysis

H2O--->1/2O2+2H+ +2e-

a.The electrons enter the electron transport chain they pass through different molecules that are reduced and then oxidized and end up in NADPH

b.The hydrogen ions build up in the thylakoid and end up passing through the ATP-synthase for this reaction to occur(ADP+H3PO4-->ATP+H2O)

c.The oxygen atom binds with another oxygen atom to form an oxygen molecule and is released in the atmosphere.

"d.) carbon dioxide and hydrogen sulfide"

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
