What molecule absorbs sunlight in photosynthesis?
Photosystem II
What is the waters role in the light reaction of photosynthesis?
Water is split to have its electrons replace the excited electron of chlorophyll, then enters photosystem II.
When during the light reaction is the water molecule split?
The water molecule is split at the beginning of the light reaction, specifically in photosystem II. This splitting of water releases electrons, protons, and oxygen as byproducts, which are essential for the rest of the light-dependent reactions to occur.
What happens in a photosystem?
In a photosystem, light energy is absorbed by pigments to excite electrons, which then pass through an electron transport chain. This creates a proton gradient across the thylakoid membrane, which drives ATP synthesis. The electrons eventually reduce NADP+ to NADPH, which is used in the Calvin cycle for carbon fixation.
What is the function of water in photosynthesis?
In order to successfully answer this question, we need to establish the symbol equation for photosynthesis: 6CO2 + 6H2O ------ C6H12O6 + 6O2 carbon dioxide + water (go to) glucose + oxygen Water is necessary to balance this equation, and to provide the hydrogen that is required for the energy.
Which molecules is split apart in photosystem II?
Water. H2O.
What molecule absorbs sunlight in photosynthesis?
Photosystem II
Where do the antennae in Photosystem II get the energy to split a water molecule?
Light from the sun
Explain how oxygen is generated in photosynthesis?
During photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The oxygen is a byproduct of the photosynthesis process. It is released into the atmosphere as a waste product.

ATP and what other molecule are produced in produced in the second stage of photosynthesis?
NADPH is the other molecule produced in the second stage of photosynthesis, known as the light-dependent reactions. Both ATP and NADPH are essential for the production of sugars in the Calvin cycle, which is the third stage of photosynthesis.
When chlorophyll p680 loses an electron from what atom does the chlorophyll receives an electron?
Chlorophyll p680 loses an electron from the primary electron acceptor, which is a nearby molecule in the photosystem II complex. The chlorophyll then receives an electron from the water molecules that are split during the light-dependent reactions of photosynthesis.
What is a gaseous reactant of photosynthesis?
oxygenOxygen gas is the product of photosynthesis. It comes from the water being split at photosystem II.
What makes the most oxygen in the process of photosynthesis?
In the process of photosynthesis, the most oxygen is produced during the light-dependent reactions, specifically in the photosystem II complex where water molecules are split to release oxygen as a byproduct.
