The ATP and NADPH are used in the Calvin cycle to fix the atmospheric CO2 into glucose. The use of water as an electron donor releases oxygen gas as a by-product. This photosynthesis wherein the use of water as an electron donor releases oxygen gas as a by-product is also called oxygenic photosynthesis.
