Oxygen and H+

the overall equation is,

2H2O ----> O2 + 4H+ + 4electrons

electrons as you know are taken up by PSII, H+ go on to form NADPH by combining with NADP+ at the end of PSI and O2 is a by product 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 process by which electrons are restored to chlorophyll after photosynthesis?

During photosynthesis, electrons from water molecules are used to replace the electrons that chlorophyll loses when it absorbs light energy. This process, known as the electron transport chain, involves a series of protein complexes that shuttle electrons and pump protons across the thylakoid membrane in the chloroplast. This generates a proton gradient that drives ATP synthesis, ultimately leading to the restoration of electrons to chlorophyll.


What is the role of water in the light reactions of photosynthesis?

Water is split in the light reactions of photosynthesis to provide electrons for the photosynthetic electron transport chain. This process releases oxygen as a byproduct. Additionally, water molecules help maintain the balance of protons and electrons within the thylakoid membrane during the light reactions.


Why photosynthesizing plants rely on water?

Plants rely on water for photosynthesis because it provides the necessary electrons during the light reactions of photosynthesis. Water is split into oxygen and hydrogen ions, which release electrons that replace those lost by chlorophyll molecules. These electrons are transported through the electron transport chain to generate ATP and NADPH, which are used to convert carbon dioxide into glucose during the Calvin cycle.

What will happen if molecules that trap electrons replace p700 molecules and those molecules become saturated with electrons?

If molecules that trap electrons replace P700 molecules, the photosystem I in the chloroplast will not be able to efficiently perform photosynthesis. If those molecules become saturated with electrons, it can lead to a buildup of reactive oxygen species and ultimately damage the photosystem. This can disrupt the electron transport chain and decrease the overall efficiency of photosynthesis.

What is water roles in the light reaction of photosynthesis?

Water is essential in the light reaction of photosynthesis as it serves as a source of electrons for photosystem II to replace those lost during electron transport. When water molecules are split in a process known as photolysis, oxygen is released, and electrons are transferred to chlorophyll in the photosystem, which initiates the electron transport chain.


Water participates directly in the light reactions of photosynthesis by?

Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.


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.


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.
