Electrons from Photosystem II (PSII) ultimately arrive at the electron transport chain, specifically at plastoquinone, which transfers the electrons to plastocyanin and then to Photosystem I (PSI). This process is part of the light-dependent reactions of photosynthesis, where the energy captured from light is used to generate ATP and NADPH. The movement of electrons through the chain also contributes to the formation of a proton gradient, which drives ATP synthesis.

Where does photo-system 2 get its replacement electrons from?
Photosystem II (PSII) obtains its replacement electrons from water molecules during the process of photolysis. When water is split into oxygen, protons, and electrons, the electrons released are used to replenish those lost by PSII after it absorbs light energy. This process also generates oxygen as a byproduct, which is released into the atmosphere.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How many electrons can be accommodated in the 5th shell of an atom under the solar system model?
In the solar system model of the atom, the maximum number of electrons that can be accommodated in any shell is given by the formula (2n^2), where (n) is the principal quantum number corresponding to the shell. For the 5th shell ((n = 5)), this calculation yields (2(5^2) = 50) electrons. Therefore, the 5th shell can hold a maximum of 50 electrons.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
What is the number of valence electrons in strontium?
Strontium has 2 valence electrons because it is part of the Alkaline Earth Metals or Group 2 of the periodic table which all have 2 valence electrons
Which sentence best describes what happens after sunlight hits photo system 2?
After sunlight hits photosystem 2, it excites electrons within photosystem 2. These electrons are then passed down an electron transport chain to photosystem 1, where they help generate ATP through a series of redox reactions.

What is the warranty details of a Smith-Victor Photo Lighting System?
It has a 2 year parts warranty.
When water molecules are split to produce the electrons needed to replace those lost by photo system 2 during photosynthesis what is produced?
Oxygen and H+ the overall equation is, 2H2O ----> O2 + 4H+ + 4electrons electrons as you know are taken up by PSII, H+ go on to form NADPH by combining with NADP+ at the end of PSI and O2 is a by product of photosynthesis
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)

What does the group number of A elements in the AB numbering system tell about valence electrons?
The group number of A elements in the AB numbering system indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on. Valence electrons are important because they determine the chemical properties and reactivity of an element.
How many S electrons are there in arsenic?
1s electrons = 2 2s electrons = 2 3s electrons = 2 4s electrons = 2 so a total of 8
How many electrons are there in 0-2?
There are 2 electrons in an oxygen ion with a charge of -2. This is because oxygen normally has 6 electrons, but when it gains 2 extra electrons to become an ion with a charge of -2, it now has 8 electrons total.
How many valance electrons are in magnesium?
Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
How many electrons does helium 4 have?
Helium-4 has 2 electrons.
