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 Which statements would be CORRECT? -triyambak.org
