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.
In a protein complex for the light reaction why is energy transferred from pigment molecule to pigment molecule to a special chlorophyll a molecule and eventually to the primary electron acceptor?
The molecular environment lets it boost an electron to a higher energy level and also to transfer the electron to another molecule
What event accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex?
The event that accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex is the excitation of electrons. When light energy is absorbed by the pigment molecules, their electrons get excited to a higher energy state. This excited state is essential for the subsequent transfer of energy to the reaction center of the photosystem for further processing.
What is the function of metal in respiratory pigment?
The metal component of a respiratory pigment is the part that actually binds to the oxygen molecule.
What energy carrier cells use to transport high-energy electrons?

What pigment is released when a hemoglobin molecule is broken apart?
When a hemoglobin molecule is broken apart, the iron pigment is released. This is what is called the -"heme" part of the molecule.
Does the carotenoids pigment help in the process of photosynthesis?
Yes, carotenoids pigments help in the process of photosynthesis, as accessory pigment molecules. They trap solar energy and transmit this trapped energy to the reaction centre molecule, that is, chlorophyll.
When a pigment molecule absorbs a photon one of its electrons?
the outer electrons which are weakly attracte towards nucleus of a pigment can absorb a photon and gets exited to its unstable higher levels. It releases more energy when it gets stabilized to its normal state. This energy can be trapped by the electron of next pigment molecules. In this way the energy gets transfered from one to other.
What is a light-absorbing colored molecule?
pigment
Which molecule is made during the light-dependent reactions?
Photosystems are the light-harvesting units of the thylakoid membrane.Each photosystem is a complex of proteins and other kinds of moleculea and includes an antenna consisting of a few hundred pigment molecules. When any antenna molecule absorbs a photon, the energy is transmitted from pigment molecule to pigment molecule until it reaches a particular chlorophyll a.Only this chlorophyll molecule is the reaction center and the first light-driven chemical reaction of photosynthesis occures.
What is chlorophyll and what is it's role in photosynthesis?
Chlorophyll is a molecule found in chloroplast. 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 is the main pigment molecule in a green leaf?
Chlorophyll
What are accesory pigments?
In plants, usually pigment is more important in the process of fertilization than any other. Pigment will attract different insects, birds, or other animals which aids in the transport of pollen to other plants for cross fertilization. However, for plants like the venus fly trap, color attracts prey.
What happens when a photon from sunlight strikes a chlorophyll a molecule?
When a photon strikes a pigment molecule such as chlorophyll, the energy from the photon is passed to the chlorophyll. This energy then continues to pass between molecules until it hits the reaction center, where the reaction of photosynthesis' glucose creation occurs.
