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.
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 does the light- dependent come from?
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts. This is where chlorophyll and other pigments absorb light energy and convert it into chemical energy in the form of ATP and NADPH. This energy is then used in the light-independent reactions to produce glucose.
Where did the electrons used in the light dependent process come from?
The electrons used in the light-dependent reactions of photosynthesis come from water molecules (H₂O). When light energy is absorbed by chlorophyll in the thylakoid membranes of chloroplasts, it energizes electrons, which are then stripped from water molecules during a process called photolysis. This process not only releases oxygen as a byproduct but also provides the energized electrons needed to drive the subsequent reactions in the photosynthetic pathway.
What is the source of h and electrons that end up in glucose?
Hydrogen atoms and electrons that end up in glucose come from the breakdown of water during the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membrane of chloroplasts, where water is split into oxygen, protons, and electrons, providing the necessary raw materials for the synthesis of glucose in the Calvin cycle.
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 the energy for the light independent reactions of photosynthesis come from?
splitting of water molecules
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.
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.
What is the source of h and electrons that end up in glucose?
Hydrogen atoms and electrons that end up in glucose come from the breakdown of water during the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membrane of chloroplasts, where water is split into oxygen, protons, and electrons, providing the necessary raw materials for the synthesis of glucose in the Calvin cycle.
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.
From where does the oxygen liberated in photosynthesis come?
The oxygen liberated in photosynthesis comes from water molecules. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons. The oxygen is released as a byproduct.
Where does the released oxygen come from in photosynthesis?
The released oxygen in photosynthesis comes from the splitting of water molecules during the light-dependent reactions in the thylakoid membrane of the chloroplasts. Water molecules are broken down into oxygen, protons, and electrons, with oxygen being released as a byproduct.
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 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 the energy come from to make at in the light reactions?
From the motion of the hydrogen ions
