Electrons that chlorophyll loses to the electron transport chain are replenished by what molecules?
The electrons that chlorophyll loses to the electron transport chain are replenished by water molecules, which are split into oxygen, protons, and electrons during the light-dependent reactions of photosynthesis.
The reactions that produce molecular oxygen (O2) take place in?
The reactions that produce molecular oxygen (O2) take place in the light-dependent reactions of photosynthesis, specifically in the thylakoid membranes of the chloroplasts. Here, water molecules are split through a process called photolysis, releasing oxygen as a byproduct.
Hydrogen molecules and oxygen molecules can be easily split by what?
Hydrogen molecules and oxygen molecules can be easily split by what electrolysis. This is the process which is used to breakdown water.
How does photolysis work?
Photolysis is a chemical reaction in which a compound is broken down by light energy. When a molecule absorbs light, it can become energetically unstable and undergo a chemical reaction that leads to its fragmentation into smaller molecules or atoms. This process is common in environmental processes such as the breakdown of pollutants by sunlight.
Where does the water come in photosynthesis?
The roots of the cell bring in water for the plant. The plant will then distribute the water.
Which molecules is split apart in photosystem II?
Water. H2O.
What molecule is split during the light reactions of photosynthesis of release oxygen?
Water molecules are split during the light reactions of photosynthesis to release oxygen. This process is known as photolysis, where water is broken down into oxygen, protons, and electrons in the presence of light.
What is the process that split water molecule in photosynthesis?
Photolysis
What is photolysis?
photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons. It is defined as the interaction of one or more photons with one target molecule.
Where does water splitting take place in photosynthesis?
The splitting of water during photosynthesis is called photolysis. It is the decomposition of water molecules by the action of light.
What happens to the water molecules when the plants absorb light energy during photosynthesis?
Water molecules are split into oxygen, protons, and electrons when plants absorb light energy during photosynthesis. This process is known as photolysis and occurs in the thylakoid membranes of the chloroplasts. Oxygen is released as a byproduct, while the protons and electrons are used to produce ATP and NADPH for the Calvin cycle.
Which molecule is split apart during the light ractions in photosynthesis?
Water or h20
How is oxygen generated in photosynthesis?
Oxygen is generated in photosynthesis through a process called photolysis, where water molecules are split into oxygen, protons, and electrons using light energy absorbed by chlorophyll in plant cells.
What is the gas that is produce during photolysis?
The gas produced during photolysis is oxygen (O2). Photolysis is the process of splitting water molecules (H2O) into hydrogen (H) and oxygen (O2) using light energy.
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.
Photolysis is a part of which cycle?
Photolysis is a chemical reaction under radiations, involved in photosynthesis.
Why is water split during the process of photosynthesis?
Water is split during photosynthesis to provide electrons needed for the production of oxygen and energy-rich molecules like ATP and NADPH. This process, known as photolysis, occurs in the thylakoid membranes of chloroplasts and is essential for plants to convert sunlight into usable energy.
