What heppens when light strikes green plant pigments?
electrons become excited
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
What happens when light hits a pigment?
When a chlorophyll molecule absorbs a photon of light, Photons strike the "antenna" of the chlorophyll molecule. This causes electrons in the photo-reaction centers that are attached to the antennas to become excited and move to a higher energy level. That's photoexcitation. The valence electrons in Magnesium (part of the chlorophyl molecule) jump to an excited state.
What are excited gases?
Excited gases are gases that have absorbed energy through processes like heat or electrical currents, causing their atoms or molecules to become energized. This leads to the electrons within the gas atoms moving to higher energy levels. When these excited electrons return to their original (ground) state, they release energy in the form of light emission, giving gases their characteristic colors in phenomena like neon lights or auroras.
What molecule when is absorbs light some of its electrons are raised to a higher energy level?
The molecule that absorbs light and raises some of its electrons to a higher energy level is typically a pigment, such as chlorophyll in plants. When chlorophyll absorbs light, particularly in the blue and red wavelengths, its electrons become excited, moving to higher energy states. This process is fundamental to photosynthesis, where the energy from light is converted into chemical energy. Other examples of light-absorbing molecules include carotenoids and various artificial dyes.

How does the electrons become excited?
Electrons become excited when they absorb energy, such as from heat, light, or electricity. This extra energy causes the electrons to move to a higher energy level away from the nucleus of an atom, creating an excited state.
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.
What effect do electrons from the magnetosphere have on atoms?
Electrons from the magnetosphere can cause atoms to become excited or ionized when they interact with them. This can lead to the emission of light, changes in chemical reactions, or damage to biological molecules. Additionally, these electrons can contribute to the creation of auroras when they collide with gases in the Earth's atmosphere.
How are electrons become excited?
Electrons become excited when they absorb energy, such as through exposure to light or heat. This additional energy causes the electrons to move to a higher energy level, creating an excited state. The electrons will eventually release this energy by returning to their original, lower energy state, emitting light or heat in the process.
WHAT HAPPENS IN THE PHOTOSYSTEM 2 protein when it is hit by a photon of light?
In photosystem II, the photon of light is absorbed by a pigment molecule, which causes an electron to become excited. This electron is then passed through a series of electron carrier molecules, creating a flow of electrons used to generate ATP and NADPH during the light-dependent reactions of photosynthesis.
Electrons that have been excited by light energy absorbed by a chlorophyll molecule?
Excited electrons in a chlorophyll molecule are transferred through a series of proteins in the thylakoid membrane, known as the electron transport chain, generating ATP and NADPH through the process of photosynthesis. These high-energy molecules will then be used in the Calvin cycle to produce glucose from carbon dioxide.
What did Planck say about energy and electron?
He said that electrons can become excited and begin to hop energy levels; when this happens an electron is in the excited state.
Where do electrons get their in photosystem 1?
In very general terms, electron transfer is caused by photoexcitation of the pigment molecules in the antenna complex. The chlorophyll and carotenoid molecules in the antenna complex become photoexcited when they absorb any wavelengths of visible light and then transmit resonant energy.
