When water molecules are split in plants where do the electrons and hydrogens ions go?
Electrons are used to replenish the electrons lost by the photosystems (electrons in photosystems are lost to the electron transport chain and eventually end up in NADPH). The protons are used by the proton pumps in the electron transport chain to create the proton gradient, which drives ATP synthesis.

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.
How is an electron involved in fuel cell?
In a fuel cell, when hydrogen gas is supplied to the anode, the hydrogen molecules are split into protons and electrons. The electrons travel through an external circuit to the cathode, creating an electric current. At the cathode, oxygen molecules combine with protons and electrons to form water. So, electrons play a key role in generating electricity in a fuel cell.
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.
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.
In photosynthesis the oxygen atoms from where are released as oxygen?
Oxygen released comes directly from the water used as a reactant. A plant enzyme splits water into protons, electrons and oxygen, with the electrons replenishing lost electrons in pigments, protons used to maintain the electrochemical gradient, and oxygen released as waste.
Where do plants get their replacement electrons from?
Plants get their replacement electrons for photosynthesis from water molecules. During the light-dependent reactions of photosynthesis, water molecules are split to release oxygen and provide electrons for the electron transport chain.
How are electrons split in a process to generate energy?
Electrons are split in a process called oxidation-reduction reactions, where they are transferred between molecules. This transfer of electrons creates a flow of energy that can be harnessed to generate electricity.
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.
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.
What has to happen to replace the electrons released by chlorophyll?
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.
What is the source of oxygen in photosynthesis in plants?
The source of oxygen in photosynthesis in plants is water. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons. The oxygen is released into the atmosphere as a byproduct of this process.
Why don't chlorophyll molecules run out of electrons?
Chlorophyll molecules do not run out of electrons because during the process of photosynthesis, they receive electrons from water molecules, which are continuously being split to release electrons. This continuous flow of electrons helps chlorophyll molecules maintain their electron supply.
What happen to the water molecules when the plants absorbs light energy during photosynthesis?
The water molecules split into hydrogen ions, electrons and oxygen atoms. The oxygen atoms join together to form oxygen molecules = oxygen gas which is released from the plant into the air. The hydrogen ions get taken up by a carrier molecule called NADP. The electrons become energised using the light energy that has been trapped by the chlorophyll and eventually join the hydrogen ions attached to the NADP. Ultimately the hydrogen ions and energised electrons join with carbon dioxide to form simple sugars = carbohydrate, from which ALL other organic compounds in the plant are made.
Which molecules is split apart in photosystem II?
Water. H2O.
Do plants split carbon dioxide molecules?
Plants do not split carbon dioxide molecules. They use a process called photosynthesis to convert carbon dioxide and water into glucose and oxygen, using sunlight as an energy source. This process occurs in the chloroplasts of plant cells.
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.
What is a waste product of photosythises?
Oxygen is a waste product of photosynthesis. During the light-dependent reactions of photosynthesis, plants produce oxygen as a byproduct when water molecules are split to release electrons and protons. This oxygen is then released into the atmosphere as a waste product.
