After electrons get excited by light a second time at photosystem II wheee do they go?

Question

A. They travel down a second electron transport chain and are donated to ADP which is then converted to ATP.
B. They travel down a second electron transport chain and are donated to NADP which becomes NADPH (an electron carrier)
C. They remain excited and then travel to photosystem II where they get even more excited until they spontaneously combust
D. They travel down a second electron transport chain and are donated to oxygen which then bonds to hydrogen ions to form water

Answer 1

After electrons are excited by light at Photosystem II in the process of photosynthesis, the correct answer is:

D. They travel down a second electron transport chain and are donated to oxygen which then bonds to hydrogen ions to form water.

In more detail, when light is absorbed by Photosystem II, electrons are excited and then transferred to an electron transport chain. Ultimately, electrons will end up reducing NADP+ to NADPH and help in forming ATP via ATP synthase. However, specifically concerning what happens to the electrons after being excited, they ultimately contribute to the generation of water (H2O) through the electron transport chain, where they reduce molecular oxygen.

Also, it's important to note that while the formation of NADPH occurs primarily later in the electron transport process, option D directly refers to the eventual role of electrons in oxygen and water formation.
