Answer: Option B. 1. photosystem II 2. photosystem II 3. photosystem I
Explanation:
Photosynthesis is the process by which plants make their own food in the presence of light utilizing carbon dioxide and water. this process occurs in chloroplast which contains green pigments called chlorophyll.
Photosystem are defined as the cluster of chlorophyll pigments found on the thylakoid membrane ( in chloroplast) which functions to collect energy and concentrate it to reaction center which further uses the energy to excite electrons and pass on to enzymes.
Photosystem II absorbs light and energy which allows the excitation of electrons and creates an electron deficiency in Photosystem II. the deficiency filled by Z protein which contain manganese that stimulates splitting of two water molecules.
NADPH formation takes place in Photosystem I. Photosystem I accepts energy from light which excites an electron and passed on to an electron acceptor called FeS. FeS then passes its e- to Ferrodoxin which donates its electron to NADP+ reductase. NADP+ reductase donates electron to NADP+ and add a proton to form NADPH to get stabilized.
Hence, the correct option is B.
