A photon of light strikes chlorophyll and an excited electron is energized to a higher level and enters the transport chain. Now, here is the ultimate reason plants use water. ( aside from turgidity and other processes ) The plant " cracks " water to get electrons to replace the electrons excited from the pigment of chlorophyll. The oxygen then becomes so much waste.
What else can I help you with?
What materials come into the chloroplast that used in the light dependent reactions?
The materials that enter the chloroplast for use in the light-dependent reactions include water molecules and light energy. Water is split into oxygen, protons, and electrons, while light energy is absorbed by chlorophyll to initiate the photosynthetic process.
Where do the excited electrons flowing through photosystem you originally come from?
The excited electrons flowing through photosystem II come from water molecules that are split during the light-dependent reactions of photosynthesis. This process, known as photolysis, releases oxygen as a byproduct and provides electrons to replace those lost when chlorophyll is excited by sunlight.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
Where do water and light come from in light dependent reactions?
In light-dependent reactions of photosynthesis, water (H₂O) is sourced from the plant's roots, where it is absorbed from the soil. Light energy is captured from sunlight by chlorophyll and other pigments in the thylakoid membranes of chloroplasts. This energy splits water molecules into oxygen, protons, and electrons, with oxygen being released as a byproduct. The electrons are then used to generate energy-rich molecules like ATP and NADPH.
When light is absorbed by chlorophyll molecules the excited electrons leave the molecule What is the source of electrons that makes chlorophyll stable again?
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.
What materials come into the chloroplast that used in the light dependent reactions?
The materials that enter the chloroplast for use in the light-dependent reactions include water molecules and light energy. Water is split into oxygen, protons, and electrons, while light energy is absorbed by chlorophyll to initiate the photosynthetic process.
What electrons are in photosynthesis?
In photosynthesis, electrons are transferred through a series of proteins in the thylakoid membrane of chloroplasts. These electrons come from water molecules and are used to drive the production of ATP and NADH, which are important molecules for the light-dependent reactions of photosynthesis.
Where do the excited electrons flowing through photosystem you originally come from?
The excited electrons flowing through photosystem II come from water molecules that are split during the light-dependent reactions of photosynthesis. This process, known as photolysis, releases oxygen as a byproduct and provides electrons to replace those lost when chlorophyll is excited by sunlight.
In photosynthesis the source of electrons is?
The electrons come from water. In the light dependent stage water is split into hydrogen ions (H+), electrons and oxygen. The electrons are passed on to chlorophyll, the H+ ions combine with NADP to form NADPH and the oxygen is released.
Where do the supply of electrons come from in photosynthesis?
The supply of electrons in photosynthesis comes from water molecules. This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis. Water molecules are broken down into oxygen, protons, and electrons, with the electrons being used to replenish the electrons lost in the photosystem II reaction center.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
Where do electrons for photosystem II come from?
Electrons for photosystem II come from the splitting of water molecules during the light-dependent reactions of photosynthesis. This process, known as photolysis, occurs in the thylakoid membranes of chloroplasts. The electrons released from water molecules replace those lost by chlorophyll molecules in photosystem II, allowing the photosystem to continue the electron transport chain and ultimately produce ATP and NADPH for the Calvin cycle.
Where do water and light come from in light dependent reactions?

Light energy is captured from sunlight by chlorophyll and other pigments in the thylakoid membranes of chloroplasts.

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.
Where do electrons come from and how it gains energy during the light reaction?
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
Where does the energy come from that excites the electrons in chlorophyll?
The energy that excites electrons in chlorophyll comes from sunlight. Specifically, chlorophyll absorbs light energy from the sun, which is then used to power the process of photosynthesis.
Where do the oxigens atoms in the O2 produced during photosynthesis come from?
The oxygen atoms in O2 produced during photosynthesis come from water molecules (H2O) that are split during the light-dependent reactions in the chloroplasts of plant cells. This process, known as photolysis, releases oxygen as a byproduct.
