Light-dependent reactions take place in the chlorophyll-containing membrane. ATP exists as a chain of carbon atoms with groups attached to it. molecules present in chloroplasts are split to release oxygen atoms, electrons, and free hydrogen ions. is the process by which phosphate groups get cleaved off of ATP. use the substances in the environment around them to obtain nutrition. Light-independent reactions use ATP and NADPH to convert carbon dioxide into .

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
