Actually the O2 comes from the water. One way to observe this is to use an isotope of oxygen like O18 and replace the O in the CO2 with the O18 and if the oxygen that is made is oxygen 18 then it is clear that it arose from the CO2. Once could then do the same thing with H2O. Another less ambiguous observation is that of thermophiles near the vents of ocean floors. Their is an abundance of H2S near these vents and the result reaction is the thermophiles producing glucose and Sulfur gas. Sulfur and Oxygen have the same valence electrons and will react the same way in order to get the electrons they need to be stable. It is safe to say that the O came from the H2O in the same way that the S comes from the H2S
What else can I help you with?
Where does the oxygen produced in the dark reaction of photosynthesis come from?
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
One of the important waste products of photosynthesis is oxygen gas Where does this oxygen gas come from?
Oxygen gas produced during photosynthesis comes from the splitting of water molecules (H2O) into oxygen (O2) and hydrogen ions (H+). This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis.
Where does oxgyen come from?
Oxygen is produced through the process of photosynthesis by plants, algae, and certain bacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for maintaining the balance of oxygen in Earth's atmosphere.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
Where do carbon hydrogen and oxygen atoms come from to form glucose during photosynthesis?
They come from CO2 and Water. They are the raw materials
Where do the oxigens atoms in the O2 produced during photosynthesis come from?
The oxygen atoms in O2 produced during photosynthesis come from water molecules (H2O) that are split during the light-dependent reactions in the chloroplasts of plant cells. This process, known as photolysis, releases oxygen as a byproduct.
Where does the oxygen produced in the dark reaction of photosynthesis come from?
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
Where does the oxygen come from photosynthesis?
Oxygen is one of the by-products of photosynthesis. It comes from the breakdown of water molecules in plants during photosynthesis.
One of the important waste products of photosynthesis is oxygen gas Where does this oxygen gas come from?
Oxygen gas produced during photosynthesis comes from the splitting of water molecules (H2O) into oxygen (O2) and hydrogen ions (H+). This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis.
What would happen if oxygen were not produced during photosynthesis?
Well, darling, if oxygen decided to take a day off during photosynthesis, we'd all be in a world of hurt. You see, oxygen is kind of a big deal for us living creatures - we need it to breathe and survive. Without oxygen being produced during photosynthesis, we'd be gasping for air faster than you can say "photosynthesis."
Where does oxgyen come from?
Oxygen is produced through the process of photosynthesis by plants, algae, and certain bacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for maintaining the balance of oxygen in Earth's atmosphere.
Where does the free oxygen it the atmosphere come form today?
It is produced by the photosynthesis of plant life.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
Oxygen atoms in the oxygen gas produced by photosynthesis comes from what?
The oxygen atoms in the oxygen gas produced by photosynthesis come from water molecules that are split during the light-dependent reactions. The oxygen molecules released are a byproduct of this process.
Where does the oxygen made during photosynthesis come from?
It comes from the splitting of water molecules.
How does oxygen occur?
If you mean how does it come to be in the atmosphere, oxygen is released into the atmosphere by plants, mostly by phytoplankton in the ocean. I you mean how is oxygen created in the first place, it is the result of lighter elements being fused together in the cores of stars.
Where does the free oxygen in Earths atmosphere come from?
The free oxygen in Earth's atmosphere primarily comes from the process of photosynthesis carried out by plants, algae, and certain bacteria. During photosynthesis, these organisms use energy from sunlight to convert carbon dioxide and water into oxygen and glucose.Approximately half of Earth's oxygen is produced by marine plants, specifically phytoplankton.
