When light hits the pigments in Photosystem II, it excites electrons within the chlorophyll molecules, raising them to a higher energy state. This energy is then used to split water molecules (photolysis), releasing oxygen and providing protons and electrons. The energized electrons are transferred through a series of proteins in the electron transport chain, ultimately contributing to ATP and NADPH production for the Calvin cycle. This process is crucial for converting light energy into chemical energy during photosynthesis.
What else can I help you with?
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 happens when light hits the pigment in photosystem ll?
When light hits the pigment in Photosystem II, it excites electrons within the chlorophyll molecules, raising them to a higher energy state. This energy is then used to split water molecules (photolysis) into oxygen, protons, and electrons. The excited electrons are transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis and ultimately contributing to the production of ATP and NADPH. This occurs during the light-dependent reactions of photosynthesis.
What happens to the electrons when sunlight hits the leaves?
When sunlight hits the leaves, the energy from the light is absorbed by chlorophyll, the green pigment in the chloroplasts. This absorbed energy excites electrons in the chlorophyll molecules, raising them to a higher energy state. These high-energy electrons are then transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis, which ultimately converts light energy into chemical energy stored in glucose.
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 light induced event during which the photoreceptor pigment breaks down to its components and retinal assumes its straighter shape?
The process you are referring to is called photobleaching. It occurs when light hits the photoreceptor pigment in the retina, causing it to break down into its components, including retinal. Retinal then assumes its straighter shape, triggering a series of chemical reactions that ultimately lead to the generation of electrical signals in the visual system.

What happens to light when it hits?
it goes nowhere
What happens when light hits a rough surface?
when light hits a rough surface it scattters.
What happens when a light hits a prism and why does it happen?
The light sctters into a spectrum.
What happens to the photo conductive layer when light hits it?
It shines by the light.
What type of reflection happens when a straight ray of light hits smooth mirrors?
When a straight light ray hits a smooth mirror, the regular reflection happens.
What happens when a ray of light hits something?
it reflects
What happens to darkness when light hits it?
it goes nowhere
How does chlorophyll make the leaf look green?
Chlorophyll is a pigment that absorbs all colors of light INCLUDING green, which is mostly reflected, but somewhat absorbed. The reflected green light hits our eyes, and the plants appear green. Don't even ask about what happens in your eyes to SEE green.
What happens to light when it hits a different medium?
The light reflects or refracts on hitting the medium.
