What is the source of oxygen gas given off during photosynthesis?

Answer 1

The Hydrogen ion is added to take the place of the energized electron in the light reaction of photosynthesis. The Hydrogen electron is taken from an H2O molecule. The oxygen is released as a waste product and the rest of the Hydrogen goes off to do work as energy is released.

Answer 2

The oxygen gas given off during photosynthesis comes from the splitting of water molecules (H2O) in the light-dependent reactions of photosynthesis. This process is known as photolysis, where water is broken down into oxygen gas (O2), protons (H+), and electrons (e-).

Answer 3

Photosynthesis is the process in which plants use energy from sunlight to transform water and carbon dioxide along with other minerals into oxygen and other organic compounds. The plant absorbs water from the ground and sunlight from the sun and then produces the oxygen and sugar, or glucose, into the environment. Thus, the source of oxygen during photosynthesis is the plant.

Answer 4

Oxygen is the *product* of photosynthesis; plants convert CO2 in our polluted air into oxygen.

" therefore, O2 released by chloroplasts comes from H2O, not from CO2".

Answer 5

The source of oxygen for photosynthesis is water.

Answer 6

Water is the source of oxygen gas that is released by a photosystem. In photosynthesis, water splitting donates electrons to power the transport chain in photosystem II.

Answer 7

The reaction isn't simple, but it originates in CO2

Answer 8

Oxygen is one of the products of photosynthesis.

Answer 9

H20
