In Photosystem II (PSII), electrons gain their energy from light absorbed by chlorophyll and other pigments within the thylakoid membrane of chloroplasts. When photons are absorbed, they excite electrons to a higher energy state, initiating a series of redox reactions. This energized electron is then transferred through a series of proteins in the electron transport chain, ultimately contributing to the synthesis of ATP and NADPH in photosynthesis.

How does electrons move photosytem II to photosytem?
Electrons move from Photosystem II to Photosystem I through a series of electron carrier molecules in the thylakoid membrane, known as the electron transport chain. During photosynthesis, light energy is used to transfer electrons along this chain, creating a proton gradient that drives ATP synthesis. This process is essential for the production of energy-rich molecules in the form of ATP and NADPH.
What is a role of photosytem 2 in the light reactions?
splitting h2o
What happens when light hits the pigment in photosytem 2?
When light hits the pigments in Photosystem II, it excites electrons within the chlorophyll molecules, raising them to a higher energy state. This energy is then used to split water molecules (photolysis), releasing oxygen and providing protons and electrons. The energized electrons are transferred through a series of proteins in the electron transport chain, ultimately contributing to ATP and NADPH production for the Calvin cycle. This process is crucial for converting light energy into chemical energy during photosynthesis.
What the maximum number of electron can go in the first three energy levels subatomic particles?
the first energy levels hold 2, 8, and 18 a total of 28 electrons
Can you draw a bohr model for fluorine?
Fluorine has 9 electrons. The first energy level holds 2 electrons, and the second energy level holds 7 electrons. The Bohr model for fluorine would show 2 electrons in the first energy level and 7 electrons in the second energy level.
