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 happened to the electrons of the pigment?
When light is absorbed by a pigment, such as chlorophyll in plants, the energy from the light excites electrons within the pigment molecule. This excitation allows the electrons to move to a higher energy state, facilitating various processes like photosynthesis. Ultimately, these energized electrons can be transferred to other molecules, initiating a series of reactions that convert light energy into chemical energy.
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?
Energy is transferred from pigment molecule to pigment molecule in the protein complex through resonance energy transfer, leading to excitation of a special chlorophyll a molecule called P680. This excitation of P680 causes the release of an electron, which is then transferred to the primary electron acceptor, initiating the electron transport chain in photosynthesis.
Is chlorophyll part of the ATP molecule?
No, chlorophyll is not part of the ATP molecule. Chlorophyll is a pigment responsible for capturing light energy during photosynthesis in plants, while ATP (adenosine triphosphate) is a molecule that stores and transfers energy within cells for various cellular processes.
How does a flavin pigment molecule work with a pH indicator?
Flavin pigment molecule can interact with a pH indicator by changing its color based on the pH of the solution. The flavin pigment undergoes a chemical reaction with the pH indicator, leading to a change in its absorption spectrum or structure, resulting in a color change that can be used to determine the pH of the solution.
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 reduced by electrons in light reactions?
In light reactions of photosynthesis, electrons are reduced by the pigment molecule chlorophyll to produce NADPH and ATP. These reduced molecules carry energy and electrons to the Calvin cycle for the synthesis of carbohydrates.
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.
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.
How is light energy is absorbed and dissipated by a pigment?
Light energy is absorbed by pigments through specific wavelengths that match the energy levels of their electrons. When light photons strike a pigment molecule, electrons are excited to a higher energy state. This absorbed energy can then be dissipated as heat, re-emitted as light (fluorescence), or used in biochemical processes, such as photosynthesis. The efficiency of these processes depends on the pigment's structure and the surrounding environment.
When light of the correct wavelength hits a photosynthetic pigment molecule?
When light of the correct wavelength hits a photosynthetic pigment molecule, it excites electrons within the molecule, elevating them to a higher energy state. This process is essential for photosynthesis, as it initiates the transformation of light energy into chemical energy. The excited electrons ultimately participate in a series of reactions that lead to the production of ATP and NADPH, which are vital for the synthesis of glucose from carbon dioxide and water. Thus, the absorption of light is a crucial step in the energy conversion process in plants.
What is the main pigment molecule in a green leaf?
Chlorophyll
