Well the hydrogen in the water molecules lose their electrons to photosystem II and oxygen gas is formed because oxygen must exists as a molecule (or else it is unstable), the electrons use the sunlight energy collected by the chlorophyll molecules to enter a transport chain which then they enter the cytochrome in which the electrons then enter another transport chain causing Hydrogen ions to enter the thykaloids from the stroma. This causes a concentration gradient that powers the ATP synthases to produce ATP. The low energy electrons enter photosystem 1 and then use the sunlight energy to enter the transport chain which travels to NADP Reductase where the electrons are attached to the NADP+ which then turns into NADPH.

Which process in the light-dependent reactions results in the release of hydrogen ions electrons and oxygen?
The process that results in the release of hydrogen ions, electrons, and oxygen during the light-dependent reactions is called photolysis of water. When light energy is absorbed by chlorophyll, it triggers the splitting of water molecules (H₂O) into oxygen (O₂), protons (H⁺), and electrons (e⁻). The oxygen is released as a byproduct, while the electrons are used in the electron transport chain, and the hydrogen ions contribute to the formation of a proton gradient used in ATP synthesis.
Photolysis occurs in the light and result in water being broken down to hydrogen ions and oxygen.?
Photolysis is a crucial process in photosynthesis where light energy is used to split water molecules into hydrogen ions (H⁺) and oxygen (O₂). This reaction takes place in the thylakoid membranes of chloroplasts during the light-dependent reactions. The released oxygen is a byproduct, while the hydrogen ions contribute to the formation of ATP and NADPH, essential for the subsequent light-independent reactions. Overall, photolysis plays a vital role in converting solar energy into chemical energy.
Does the dark reactions of photosynthesis release oxygen?
Molecular oxygen is formed in the light dependent reaction of photosynthesis. This occurs in the electron transport chain in the protein complexes of the thylakoid membrane. The water splitting complex yields oxygen, hydrogen ions and electrons.
When does photosynthesis produce oxygen?
Light Dependant ReactionCarbon dioxide + H2O + SUNLIGHT => NaDPH + O2 + ATPThen the NaDPH and the ATP goes to the dark reactions, or the Calvin-Benson Cycle.
Where do the hydrogen ions for the photosystems of the light-dependent reactions originate?
The hydrogen ions for the photosystems of the light-dependent reactions originate from water molecules during the process of photosynthesis.
During the light dependent reactions H ions build up in the?
Thylakoid space when water molecules are split.
Where do the hydrogen ions comes from for the photosystems of the light-dependent reactions?
splitting of water molecules
Is not produced in the light-dependent reactions of photosynthesis A. NADPH B. sugars C. ATP D. oxygen?
hydrogen ions
The movement of hydrogen ions into the thylakoid space creates what?
The movement of hydrogen ions into the thylakoid space creates a proton gradient. This proton gradient is essential for driving ATP synthesis during the light-dependent reactions of photosynthesis.
Which process during photosynthesis involves addition of hydrogen?
The process during photosynthesis that involves the addition of hydrogen is the reduction of NADP+ to NADPH. This occurs during the light-dependent reactions, where light energy is used to drive the conversion of NADP+ into NADPH by adding hydrogen ions and electrons from water.
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 does the energy come from to make at in the light reactions?
From the motion of the hydrogen ions
Does the dark reactions of photosynthesis release oxygen?
Molecular oxygen is formed in the light dependent reaction of photosynthesis. This occurs in the electron transport chain in the protein complexes of the thylakoid membrane. The water splitting complex yields oxygen, hydrogen ions and electrons.
A compound that is split during photosynthesis is?
Water is the compound that is split during photosynthesis, producing oxygen and hydrogen ions in the process. This splitting of water is a crucial step in the light-dependent reactions of photosynthesis that ultimately leads to the production of ATP and NADPH for use in the Calvin cycle.
Difference between light dependent reactions and light independent reactions in photosynthesis?
I'm assuming you're talking about photosynthesis. The main difference can be seen in the terms. Light dependent need light to react, light independent do not. In the light reactions the photon of light hits the chlorophyll which excites an electron that goes into the electron transport chain. This electron comes from water being split into H+ ions and oxygent gas. A small amount of ATP is produced and NADPH is produced. In the dark reaction, called the Calvin cycle, the ATP and NADPH produced by the light reaction is used to combine RUBP with CO2 to make glucose.
Where does chlorophyll pick up electrons?
Chlorophyll picks up electrons in the process of photosynthesis, specifically during the light-dependent reactions in the thylakoid membranes of chloroplasts. When chlorophyll absorbs light energy, it excites electrons that are transferred through a series of molecules, eventually leading to the generation of ATP and NADPH for the Calvin cycle.
