D.the protein ATP synthase

Answer 1

C

Answer 2

The most appropriate answer would be C.electron carriers such as NADP⁺.

High energy electrons are transported through electron transport chain embedded in a thylakoid membrane in order to produce energy rich compounds such as ATP and NADPH.

It is also called as light dependent reaction of photosynthesis. It includes four major protein complexes: photosystem II, photosystem I, cytochrome b6f complex, and ATP synthase.

The electron first gets excited from chlorophyll a present in the reaction center (P₆₈₀ and P₇₀₀) of two photosystems (PS II and PS I) . The electron in PS II is replenished by photolysis of water.

Different electron carriers (such as plastoquinone, plastocyanin, pheophytin, chlorophyll A₀ etc) are present which help in transferring this high energy electron from one complex to another. NADP⁺ is the final acceptor of the electron and gets reduced to NADPH.

NADPH and ATP are then used in dark reaction in order to fix carbon into sugars.
