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.
Which parts of the atom move around the nucleous?
Electrons. They have a negative charge.
What is a role of photosytem 2 in the light reactions?
splitting h2o
How many electrons are in iron (II)?
Iron (II) refers to the iron ion with a +2 charge, meaning it has lost two electrons compared to its neutral state. A neutral iron atom has 26 electrons, so an iron (II) ion has 24 electrons. Therefore, iron (II) contains 24 electrons.

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.
Do the electrons move?
Yes, electrons move within an atom as they orbit the nucleus. In conductive materials, electrons can also move freely, creating an electric current.
Electrons move in a circuit and have millions and millions of what?
Electrons move in a circuit and have millions and millions of collision's.
What gives metals the ability to conduct?
The fact that some electrons can move about easily.The fact that some electrons can move about easily.The fact that some electrons can move about easily.The fact that some electrons can move about easily.
Where do electrons moving along the inner membrane move to?
Electrons move around the nucleus of an atom or are exchaned between them. They do not move along membranes
