What happens when a photon of light hits photosystem ii? a. the water-spitting enzyme is released into the inner space. b. a channel in the photosystem || protein allows the light to pass into the thylakoid. c. water molecules enter the thylakoid membrane and are split. d. an electron is excited and enters the electron transport chain.

The correct answer is option D.

Explanation:

Photosystem II is a special pigment-protein complex that utilizes a photon to excite the electron and transfer of electrons from water to PQ or plastoquinone. That resulting in the generation of oxygen and the release of reduced PQ into the photosynthetic membrane.

Steps involved in photosystem:

When a photon hit photosystem II, light energy absorbed by one of the pigments in photosystem II, energy is carried from one pigment to another and reach down to the reaction center .

ATP synthesis

Light absorption in PSI

NADPH formation.

Thus, The correct answer is option D.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
