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?
In photosynthesis, the electrons from the chlorophyll are excited by the sunlight
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.
Why selenium is photo conductor?
when light falls on the it its electrons become excited and become free for conductivity that's why selenium is a photo conductor
Where do electrons get their energy in photo system 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.
Electrons in pigment molecules become excited when exposed to?
Ultraviolet Light

What will happen if molecules that trap electrons replace p700 molecules and those molecules become saturated with electrons?
you will die o.O

Electrons that have been excited by light energy absorbed by a chlorophyll molecule?
Some of the electrons become excited. means that they have comparatively more energy. the flow of energy takes place through these excited electrons. these are transferred form the reaction center chlorophyll to the primary electron acceptors.
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.
Why selenium is photo conductor?
when light falls on the it its electrons become excited and become free for conductivity that's why selenium is a photo conductor

When an atom absorbs enough energy electrons move to an orbital?
The electrons become excited and move to higher energy orbitals.
How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.
