Chlorophyll molecules donate electrons to an electron acceptor in the reaction center.

Explanation:

Light reaction of photosynthesis takes place in the reaction centre. Light reaction may comprises of several proteins such as pheophytin, chlorophyll and quinones which act as light absorbing molecules.

The light reaction is the core of photosynthesis that produces ATP and NADPH to carry out the dark reaction for the production of high energy carbon molecules. During light reaction light photons are captured by photosystems such as photosystem I and II of chlorophyll in green plants. This photon cause the excitation of electron that flows through the electron transport chain from higher potential to lower potential and energy released by it is utilized for creating the gradient potential of H+ ions across the membrane. This gradient potential difference of H+ ions is used for the production of ATP through ATP synthase complex.

So chlorophyll molecules donate electrons to electron acceptors through the excitation of electrons from light photons in the reaction center.

Chlorophyll molecules donate electrons to an electron acceptor in the reaction center

Explanation:

The light dependant reactions of photosynthesis uses light energy to make ATP and NADPH, needed for the next stage of photosynthesis.

Reaction center of photosynthesis are primarily found in photosystem I and photosystem II, is an integral membrane pigment-protein complex that execute the primary energy conversion reactions of photosynthesis. They capture energy (either from sunlight or transferred as excitation energy via light-harvesting antenna systems) and converts it into motion of energized electrons. At the center is a key chlorophyll molecule. When it absorbs light, one of its electrons is promoted to a higher energy. The electrons then goes downhill through several other pigmented molecules and then finally to plastoquinone B. This then delivers its electrons to the next link in the electron-transfer chain.
