Solution
The correct option is D Cytochrome
The photochemical phase of photosynthesis results in the synthesis of assimilatory (ATP) and reducing (NADPH2) power. The light energy leads to the light dependent split of water, which releases electrons. These electrons are passed through a series of electron carriers like two photosystems, plastoquinone, cytochrome b6-f complex and plastocyanin and are finally passed on to ferredoxin for donation to oxidised NADP to form reduced NADPH2. Cytochromes are also involved in respiratory electron transport system located in the inner mitochondrial membrane.
