What reaction gives rise to the oxygen produced in photosynthesis?
Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air.
Where does the oxygen produced in photosynthesis come from?
The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.
What are 2 products of photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose.
When oxygen is released as a result of photosynthesis?
light reactions
Oxygen is released during the light reactions of photosynthesis. Water, or H2O , is split during the light reactions into gaseous oxygen, or O2 , as well as H+ protons and electrons. The electrons reduce the P680+ pigments in photosystem II once they donate their excited electrons to the primary electron acceptor.
How much oxygen is produced in photosynthesis?
It takes six molecules of CO2 to produce one molecule of glucose by photosynthesis, and six molecules of oxygen are released as a by-product. A glucose molecule contains six carbon atoms, so that’s a net gain of one molecule of oxygen for every atom of carbon added to the tree.
At what stage of photosynthesis is oxygen produced?
Photosynthesis occurs in two stages. During the first stage, the energy from sunlight is absorbed by the chloroplast. Water is used, and oxygen is produced during this part of the process. During the second stage, carbon dioxide is used, and glucose is produced.
Is oxygen a product of photosynthesis?
The chemical reactions are the reverse of photosynthesis, using a glucose molecule and six oxygen molecules (12 atoms) as inputs. Energy is released along with some carbon dioxide and water. Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.
What are the end products of photosynthesis?
Though the final product of photosynthesis is glucose, the glucose is conveniently stored as starch. Starch is approximated as (C6H10O5)n, where n is in the thousands. Starch is formed by the condensation of thousands of glucose molecules.
Which gas do plants give off during photosynthesis?
Oxygen
Oxygen is released during the process of photosynthesis.
Which country is the largest producer of oxygen?
In 2019, Top exporters of Medical oxygen are Belgium ($31,855.54K , 352,806,000 m³), France ($24,658.77K ), European Union ($9,146.10K ), Germany ($8,279.38K , 48,330,600 m³), Portugal ($8,259.62K , 28,519,200 m³)….Medical oxygen (280440) exports by country.

How are oxygen atoms released during photosynthesis?
Oxygen gas produced during photosynthesis originates as a byproduct of nitrogen-fixing bacteria. oxygen atoms are released by the metabolism of carbohydrates. oxygen atoms contained in water molecules. oxygen atoms contained in carbon dioxide are released when the carbon is fixed. a molecule of chlorophyll oxidized by a photon.
How are sugar molecules produced in photosynthesis by plants?
By David Chandler; Updated April 05, 2018. plants image by Dave from Fotolia.com. Photosynthesis is the process by which plants and some bacteria and protists synthesize sugar molecules from carbon dioxide, water, and sunlight. Photosynthesis can be divided into two stages—the light dependent reaction and the light independent (or dark) reactions.
What happens to carbon dioxide and water during photosynthesis?
The process During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Where does the energy from light go in photosynthesis?
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.
