Oxygen-Evolving Organisms Have two Photosystems that Operate in Series, explain by emerson that is the Photosystem I preferentially absorbs far-red light of wavelengths greater than 680 nm; photosystem II preferentially absorbs red light of 680 nm and is driven very poorly by far-red light; Another difference between the photosystems is that,
a.) Photosystem I produces a strong reductant, capable of reducing NADP+, and a weak oxidant
b.) Photosystem I produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem II
c.) Photosystem II produces a strong reductant, capable of reducing NADP+, and a weak oxidant
d.) Photosystem II produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem I

In the higher excited state, chlorophyll is extremely unstable; it rapidly gives up some of its energy to the surroundings as heat, and enters the lowest excited state, the excited chlorophyll has four alternative pathways for disposing of its available energy: fluorescence, Heat loss, energy transfer, photochemistry; all process takes place in which wavelength,
