they move through an electron transport chain to photosystem 1
What else can I help you with?
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.
After sunlight hits photosystem 2 which is the best description of what happens?
During photosynthesis, light energy from the sun is absorbed by photosystem II, which excites electrons. These high-energy electrons are then transferred through a series of proteins in the electron transport chain, creating energy used to produce ATP and ultimately leading to the splitting of water molecules to release oxygen.
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
What happens to water molecules as a result of the actions of the photosystem II enzyme?
Photosystem II enzyme splits water molecules into oxygen, electrons, and protons. This process is known as photolysis, and the oxygen is released as a byproduct while the electrons are transferred through the electron transport chain to generate ATP and NADPH for the light-dependent reactions of photosynthesis.
What happens to electrons when pigments in photosystem absorb lights?
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.
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 happens when light strikes a photosystem?
When light strikes a photosystem, it excites electrons in the chlorophyll molecules within the photosystem. These energized electrons are then passed through a series of electron carriers, generating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH. This process is called photophosphorylation and is a key step in photosynthesis.
When chlorophyll absorbs light energy what happens to its electrons?
It becomes excited.
What happens in a photosystem?
In a photosystem, light energy is absorbed by pigments to excite electrons, which then pass through an electron transport chain. This creates a proton gradient across the thylakoid membrane, which drives ATP synthesis. The electrons eventually reduce NADP+ to NADPH, which is used in the Calvin cycle for carbon fixation.
What happens in the photosystem protein when it is hit by a photon of light?
When a photosystem protein is hit by a photon of light, it excites an electron within the pigment molecules in the protein. This electron is then passed along a series of molecules in the photosystem, creating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH.
What happens when hydrogen atom absorbs a quantum of enery?
The electrons move up to a higher energy level.
Are electrons are energized twice during photosynthesis?
Yes because there are two photosystems (clusters of chlorophyll) which is where the sunlight is absorbed from, the electrons are energized at both times because sunlight contains photons which are the molecules that energize the electrons in the first place
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 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.
