What is the function of water in photosynthesis?

Answer 1

It doesn't necessarily have a function, but is a molecule that reacts with carbon dioxide to produce glucose.

Water is one of the reactants in photosynthesis, it provides the hydrogen needed to form glucose (a hydrocarbon).

#"carbon dioxide" + "water" + "energy" -> "glucose" + "oxygen"# #6"CO"_2 + 6"H"_2"O" -> "C"_6"H"_12"O"_6 + 6"O"_2#

Water and carbon dioxide enter the leaf through the stomata (small holes on the underside of the leaf that are controlled by gaurd cells) by diffusion.

The water is split during the light reaction to form oxygen gas and hydrogen ions. The hydrogen ions are used by the chloroplast to produce ATP.

The hydrogen is also important because it can combine with carbon (from carbon dioxide) to produce glucose.

Piper Anderson

In the light-dependent reactions of photosynthesis, water is a reactant that is broken down into protons (H+) and oxygen (O2), which are released as byproducts and used to produce ATP and NADPH, molecules that provide energy and reducing power for the Calvin cycle, the second stage of photosynthesis.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
