in forming molecules of NADPH
The source of electrons that makes chlorophyll stable again is water. The process of photosynthesis involves the splitting of water molecules to provide electrons, which are then used to replace the electrons lost from the chlorophyll molecule during absorption of light.
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
Light is absorbed by the chlorophyll.
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.
Electrons released by chlorophyll during photosynthesis are replaced by splitting water molecules in the light-dependent reactions of photosynthesis. This process, known as photolysis, generates oxygen and protons, while providing electrons to keep the photosystem working.
As the sunlight hits the chlorophyll molecules sunlight is absorbed by a molecule of chlorophyll electrons in the molecule interact with photons of light and are raised to a higher energy level. The electrons are passed from one molecule to another in an electron transport chain producing ATP and NADPH. In case you don't know ATP is what cells mainly use for energy and NADPH is use as an electron carrier.Light energy is transferred to the electrons inthe chlorophyll molecule, raising the energy of theseelectrons. These high-energy electrons make photosynthesiswork.100% correct answer. Got it from answer book :D. You might want to change some words though since I got it straight from answer book...Its 9th grade biology btw
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 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.
During photosynthesis, water molecules are split into oxygen, protons, and electrons in a process known as photolysis, releasing oxygen as a byproduct. Sunlight is absorbed by chlorophyll in the chloroplasts of plant cells and provides the energy needed to convert carbon dioxide and water into glucose and oxygen.
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.
The pigment molecule that transfers electrons during the light reaction is chlorophyll. Chlorophyll absorbs light energy and transfers electrons to the reaction center of the photosystem, initiating the flow of electrons through the electron transport chain. This process is essential for the conversion of light energy into chemical energy during photosynthesis.
Chlorophyll primarily absorbs light in the blue (around 430 nm) and red (around 660 nm) regions of the electromagnetic spectrum. This absorbed light excites the chlorophyll molecules, boosting electrons to a higher energy state, which is crucial for the process of photosynthesis. The energy from the light is used to drive the conversion of carbon dioxide and water into glucose and oxygen.
