Which of the following statements correctly describes a reaction associated with photosystem II? A)Light energy excites electrons in the thylakoid membrane electron transport chain. B)Electrons released from the P680 chlorophyll are replaced by electrons derived from water. C)The P680 chlorophyll donates a pair of electrons directly to NADP⁺,producing NADPH. D)Electrons are passed from the P680 chlorophyll to oxygen (O₂).

Question

Quizplus · Accepted Answer

In photosystem II, light energy excites electrons in the P680 chlorophyll, causing it to release electrons. These electrons are then replaced by electrons derived from water, which is split into oxygen and hydrogen ions. This process is known as photolysis and generates oxygen as a byproduct. The excited electrons move through the thylakoid membrane electron transport chain, generating a proton gradient and eventually leading to the production of ATP and NADPH.
