What is a role of photosytem 2 in the light reactions?
splitting h2o
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.
Where do electrons get there energy in photosytem 2?
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.
What goes in the electron transport chain?
In the electron transport chain, electrons are passed from one protein complex to another, using energy to pump protons across a membrane. This creates an electrochemical gradient that is used to generate ATP in a process known as oxidative phosphorylation. Oxygen is the final electron acceptor in the chain, which combines with protons to form water.
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 is photosytem?
Photosystem is a biochemical mechanism in plants that chlorophyll absorbs light energy for photosynthesis.

What is a role of photosytem l in the light reactions?
It is placed as second photosystem in the light reactions of plants, algae and some bacteria. It is an integral membarne protein complex. It functioning the electron transfer from plastocyanin to ferredoxin. Like PSII, PSI also uses light energy to excite electrons.

What stage of meiosis II is skipped?
The stage of meiosis II that is skipped is interphase. Meiosis II immediately follows meiosis I and consists of prophase II, metaphase II, anaphase II, and telophase II.
What is ii?
As a Roman numeral ii or II is equivalent to 2
