What is the source of energy for excited electrons?
There are several opportunities to excite electrons within an atom or a molecule. The energies to excite a single electron in an atom start at roughly 10-19J, which is approximately the energy of red light. Though, electrons can also be excited by any energies above roughly 10-25J (radar waves), dependent on the material. This also includes thermal excitation. For example, any material that glows does emit light, which is caused by excited electrons that fall back into a non-excited state. However, the usual source of energy used to excite electrons is electromagnetic radiation between 200 and 700 nm, which is ultraviolet and visible light. This is the predominant energy range that excites electrons in atoms and molecules without splitting the electrons apart of those. Thus, the colour of materials is (amongst other things) a result of the electron excitation, caused by partial absorption of light. (Please also follow the provided links for more details.)
What heppens when light strikes green plant pigments?
electrons become excited
What does it mean for an electron to be excited?
The electron starts to move faster.Not a bad try... but to rephrase it- the electron, when excited, jumps to a lower energy orbital and gives off a photon of a certain frequency. this helps it lose the 'excess' energy and re- stabilize.
What happens to the 2 NADH produced during glycosis?
NADH can lose an electron and become NAD. The formation of NAD is also associated with oxidative stress from the formation of OH- as it leaks from the electron transport chain.
How would blocking of the electron transport chain affect a plant?
Electrons become diverted from the transport chain, releasing excess energy into the cell and destroying cell membranes. Another herbicide action is creation of superoxide radical which is highly reactive.
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.
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.
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.
What molecule does oxygen became a part of at the and of the electron transport chain?
The oxygen combines with two hydrogens and the requisite electrons to become water.

What molecule does oxygen become a part of at the end of the electron transport train?
By combining both electrons and protons, oxygen forms into water. O2 + 4e- + 4H+ > 2H2O

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.

Electrons in pigment molecules become excited when exposed to?
Ultraviolet Light
What are the 2 energy carriers that enter the electron transport chain and their energy can be transferred to ATP?
FAD and NADHThe pick up electrons, with attendant protons, to carry into the transport chain and become,FADH and NADH2
