What does light do to oxygen in photosynthesis?

Answer 1

There is no role of oxygen in photosynthesis. Oxygen is used as the terminal electron acceptor during respiration. Oxygen is the by-product of a water molecule breaking down in the very beginning of photosynthesis to supply photosystem II with electrons.

Answer 2

The waste product of photosynthesis. Water is " cracked " to provide replacement electrons for those lost by excitation of the chlorophyll pigment by photons. Oxygen is thus waste here, but in oxidative phosphorilation the glucose molecule, made by photosynthesis, still provides the oxygen that becomes the final electron acceptor.

Answer 3

Photosynthesis is made up of the light dependent and light independent reactions. Both of these contain separate endergonic and exergonic reactions. First, the light dependent reaction contains two separate endergonic reactions. At the first electron transport chain where ADP is bonded to a third phosphate to make ATP through chemiosmosis energy is required because it takes energy to move hydrogen ions against the concentration gradient of the thylakoid membrane. The second endergonic reaction in the light dependent reaction is occurs in the second electron transport chain when NADP is bonded to a hydrogen ion to make NADPH. This is endergonic because it takes energy to bond to molecule/atoms together.

Light doesn't do anything to oxygen. It is however used to split the original H2O atom to create oxygen

Answer 4

Oxygen doesn't do anything during photosynthesis, oxygen is produced when photosynthesis occurs and is then released from the plants.

Answer 5

O2 or Oxygen is a by-product of photosynthesis, it's a chemical change from CO2 or carbon dioxide

Answer 6

plants take in the oxygen and let out the carbon dioxide during photosynthesis

Answer 7

Oxygen is expelled as waste.

Answer 8

It gets released into the Atmosphere.
