What is the role of water during photosynthesis?

Answer 1

Light reactions

Chloroplasts harness light energy to split H2O (water) to release O2 (oxygen). This reaction takes place in the thylakoid membranes of the chloroplast.

Dark reactions

This is the calvin cycle where CO2 (carbon dioxide) is converted into CH2O (sugars). This reaction takes place in the stroma (matrix) of the chloroplast.

Answer 2

Unfortunately water is not used in photosynthesis, I imagine you are trying to say How is light used in photosynthesis? Well the answer to this is that chloroplasts inside the plant's leaves absorb the light and create plant food out of it.

Answer 3

There are two stages in photosynthesis: The Light Dependent and the Light Independent Reactions. In the Light Dependant Reaction, sunlight charges and electron which flows through an electron transport chain along the thylakoid membrane of a chloroplast. In the first photosystem, the electron results in the formation of a water molecule by providing the energy for two hydrogen ions to combine with a single oxygen ion.

Answer 4

The role of water H20 is to donate H+ ions to the cell, which are subsequently used in pathways to generate energy in the form of ATP. This is why oxygen is released during photosynthesis.

Answer 5

• IT makes the plant happy
• not really
• it does but not in photosynthesis
• who Eva wrote this is wrong/right
• :)
• LEX NASTY OUUT :)

Answer 6

H20 donates electrons to the photosynthesis 2 (PSII) structure to keep the process going. -BigAndBeefy

Answer 7

Photosynthesis only uses the hydrogen from the water molecule. The oxygen is released. The hydrogen is combined with carbon dioxide to form the primary building block called glucose.

Answer 8

Water is the source of the hydrogen which is combined with carbon from carbon dioxide to make glucose molecules (composed almost entirely from those two elements).

Answer 9

It is in the light reaction. It is happening in the grana.
