What happens in photopigments when they absorb photon energy?
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 are the different pigments in plants?
The different pigments that are present in plants:1) Chlorophyll a- Is the pigment directly involved in harvesting light energy. It absorbs blue-green light.2) Chorophyll b- Absorbs yellow-green wave lengths.3) Caroteniods- Absorbs blue/violet, and reflects Orange.4) Xanthophylls- Absorbs yellow pigments.5) Anthocyanins- This is found in the vacuoles. Absorbs red, violet, and blue.All other the pigments are accessory pigments because they pass their absorbed energy to chlorophylla or they play an protective role.
What happens chemically when chlorophyll absorbs light energy?
When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high-energy electrons make photosynthesis work
After sunlight hits photosystem 2 which is the best description of what happens?
solar energy changes adp into atp.
Which happens last in the process of photosynthesis?
Photosystem I or the p700 complex is used last in photosynthesis.

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.
When chlorophyll absorbs light energy what happens to its electrons?
It becomes excited.

What happens when pigments absorb light?
the electrons of the pigment molecules excite, then the energy dissipates as heat.
Which photosystem is used first in photosynthesis?
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis

What happens when hydrogen atom absorbs a quantum of enery?
The electrons move up to a higher energy level.
What happens when an excited electron is passed to an electron acceptor in a photosystem?
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
What happens after photosynthesis?
- ATP is the end result after Photosystem II. - NADPH is the end result for Photosystem I. They are sources of energy & they use sugars for energy storage/transport.
What happens when photon is absorbed by atom?
When an atom absorbs a photon its energy is transferred to outer shell electrons. The result will be the transition of an electron to a higher energy state.
