A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron allows it to break free from an atom of the chlorophyll molecule.
The energy is picked up by ADP and a phosphate forming ATP. when sunlight excites electrons in chlorophyll how do the electrons change the energy of the electrons increases where do the light-dependent reactions take place thylakoid membrane Photosystem ll (summary)
When a chlorophyll molecule absorbs the photon from sunlight, its electron gets to a higher energy state. In this state, the electron is very unstable and will be transferred to other molecules by electron donors and acceptors by a series of redox reactons called the Electron Transport chain.
Photons of sunlight are absorbed by electrons. When this light energy is absorbed, it jumps from its base energy level to a higher level. When chlorophyll in plants then process this energy, the electrons will return to their base energy level.

When sunlight excites electrons in chlorophyll How do the electrons change quizlet?
when sunlight excites electrons in chlorophyll, how do the electrons change? light is absorbed, increasing the energy of electrons. the electrons are then passed down the electron transport chain. Enzymes break H2O molecules into 2 electrons, 2 H+ ions, and 1 oxygen atom.
What happens to excited electrons in photosynthesis?
The reaction center chlorophyll of photosystem I transfers its excited electrons through a series of carriers to ferrodoxin, a small protein on the stromal side of the thylakoid membrane. The enzyme NADP reductase then transfers electrons from ferrodoxin to NADP+, generating NADPH.
What happens when light excites chlorophyll?
During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.
Does chlorophyll excite electrons?

Where do you find a carrier molecule?
Carrier proteins are membrane transport proteins along with the channel proteins. As membrane transport proteins, they are located in biological membranes and their primary function is to move molecules from one site to another.
What do carrier molecules bring?
Carrier molecules bring specific amino acids to add to the growing protein in the correct order. There are only about 20 different naturally-occurring amino acids. Each protein molecule has hundreds, or even thousands, of amino acids joined together in a unique sequence. It is then folded into the correct unique shape.
