Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water.
For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
What else can I help you with?
What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
Light excites in photosynthetic pigments?
Light excites two sets of photosynthetic pigments. These are photosystem 1 (PS1) and photosystem 2 (PS2). PS1 is excited by photons at about 700 nanometers, while PS2 is excited at about 680 nanometers.
What is the start of photosynthesis?
pigments in photosystem II absorb light
What is true about the light reaction?
photosynthesis begins when pigments in photosystem i absorb light.
How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
Is the beginning of photosynthesis pigments in photosystem absorb light?
Yes, that is correct. The light energy excites electrons in photosystems and these electrons enter the electron transport chain to make ATP. These electrons eventually end up in NADPH and photosystems are replenished with electrons obtained from splitting water.
Where do electrons get their energy in photosystem II?
From energy in photons
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
All about orgenelle?
Pigments in the orgenelle absorb the sun's energy, which excites the electrons.
In a photosystem clusters of chlorophyll a chlorophyllb and carotenoid pigments function most like what?
Clusters of chlorophyll a, chlorophyll b, and carotenoid pigments in a photosystem function most similarly to antenna complexes in capturing and transferring light energy. These pigments absorb light at different wavelengths and transfer the energy to the reaction center chlorophyll to drive the photosynthetic process.
What is the cluster of light harvesting complexes in a thylakoid?
The cluster of light harvesting complexes in a thylakoid is called a photosystem. It consists of chlorophyll molecules and other pigments that absorb light energy and transfer it to reaction centers where photosynthesis takes place. Photosystem I and Photosystem II are the two main types found in the thylakoid membrane.
How do electrons gain energy in photosystem I?
They absorb photons.
