What happens when light energy excites electrons in photosystem II?

Oxygen ions are released into the thylakoid space.

Water molecules are created.

Electrons are released into the electron transport system.

Hydrogen is released as waste.

C. Electrons are released into the electron transport system.

Explanation:

Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.

When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.

Hence, the correct option is C.

what's the question ?

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
