What happens to electrons when pigments in photosystem absorb lights?
Wiki User
∙ 7y ago
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.

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 energy in photosystem I?
They absorb photons.
What happens when pigments absorb light?
the electrons of the pigment molecules excite, then the energy dissipates as heat.
How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
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.
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.
All about orgenelle?
Pigments in the orgenelle absorb the sun's energy, which excites the electrons.
What happens in photopigments when they absorb photon energy?

Antennalike energy-harvesting unit in a thylakoid?
Antenna pigments, chlorophyll a, chlorophyll b, and carotenoids, that are light harvesting antennas in the thylakoid. After the antenna pigments absorb light energy and transformed as chemical energy then transfered to the reaction center complex.
What is true about light dependent reaction?
photosynthesis begins when pigments in photosystem i absorb light.
