How is O2 involved in photosynthesis?
Oxygen (O2) is produced as a byproduct of the light-dependent reactions of photosynthesis. During this process, water molecules are split, releasing oxygen atoms that combine to form O2 gas. This oxygen is then released into the atmosphere as a waste product of photosynthesis.
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.
How can you explain how we know that the oxygen released in photosynthesis comes from water?
During the process of photosynthesis, scientists use isotopic labeling experiments to track the origin of oxygen atoms in the oxygen gas released. By using water molecules labeled with a specific isotope, such as oxygen-18, researchers can confirm that the oxygen gas produced during photosynthesis indeed comes from water molecules. This experimental evidence supports the understanding that the oxygen released in photosynthesis originates from water.
How many oxygen atoms are needed to start photosynthesis reaction?
In the first step of photosynthesis, which is light-dependent, two water molecules are needed to start the reaction. Each water molecule contains two oxygen atoms, so a total of four oxygen atoms are needed.
How does the process of photosynthesis involve the splitting of water molecules?
During photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The water molecules are split into hydrogen and oxygen atoms through a process called photolysis, which occurs in the thylakoid membranes of chloroplasts. The oxygen atoms are released as oxygen gas, while the hydrogen atoms are used to create energy-rich molecules that drive the production of glucose.
During photosynthesis water molecules are split into atoms of oxygen and what?
Since water is comprised of two hydrogen atoms and one oxygen atom, when it is split into atoms by plants during photosynthesis the only other atoms other than oxygen that are produced are hydrogen atoms.

Oxygen is given off as a by product?
During the process of photosynthesis, plants release oxygen as a byproduct. This oxygen is produced when water is split into oxygen and hydrogen atoms during the light-dependent reactions of photosynthesis. The oxygen released by plants is essential for all living organisms that require oxygen for respiration.

This experimental evidence supports the understanding that the oxygen released in photosynthesis originates from water.
What is the formula of the oxygen particle produced?
The formula for the oxygen particle produced is O2, which consists of two oxygen atoms bonded together.
How many oxygen atoms are left after photosynthesis?
6
Where do the oxygen atoms in the CO2 come from?
The oxygen atoms in CO2 come from the process of photosynthesis in plants. During photosynthesis, plants take in carbon dioxide from the air and water from the soil, and using sunlight as energy, convert them into glucose (sugar) and oxygen.
Could oxygen be produced from a chemical reaction if none of the reactants contained oxygen atoms?
No.
How many oxygen atoms are needed to start photosynthesis reaction?
In the first step of photosynthesis, which is light-dependent, two water molecules are needed to start the reaction. Each water molecule contains two oxygen atoms, so a total of four oxygen atoms are needed.
What is combined with two oxygen atoms and helps plants engage in photosynthesis?
Carbon dioxide is combined with two oxygen atoms to help plants engage in photosynthesis. During this process, plants take in carbon dioxide from the air and convert it into sugars and oxygen with the help of sunlight.
The life cycle of an oxygen molecule?
Oxygen molecules are constantly cycling through the environment. They are produced by plants during photosynthesis, consumed by animals during respiration, and released back into the atmosphere. Eventually, oxygen molecules can be broken down by UV radiation into individual oxygen atoms.
