Does the oxygen in glucose come from water?

Does the oxygen in glucose come from water?

Therefore, the oxygen present in glucose is not obtained from water. The fixation of six carbon dioxide by six turns of the Calvin cycle facilitates the removal of one molecule of glucose from the pathway. Thus, the oxygen in glucose comes from carbon dioxide from the atmosphere.

Where does oxygen come from in photosynthesis to form glucose?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) 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.

Are oxygen and glucose made from photosynthesis?

The products of photosynthesis are glucose and oxygen. Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2).

Which of the following is the source of the oxygen released during photosynthesis?

water
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.

What does glucose and oxygen produce?

Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

How does oxygen react with glucose?

Glucose reacts with molecular oxygen to produce carbon dioxide and water. The carbon atoms in glucose are oxidized. That is, they lose electron and go to a higher oxidation state.

What is the source of oxygen in glucose?

The oxygen in the glucose molecule comes from the carbon dioxide, which is used in the Calvin Cycle. As you mentioned, the oxygen in water is broken down in the non-cyclic phosphorylation process to obtain an electron which can be used in the photosystem I and II to form ATP and NADPH.

What happens to glucose and oxygen after 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.

What happens to glucose produced in photosynthesis quizlet?

What happens to the glucose produced during photosynthesis? Some of the glucose produced in photosynthesis is used immediately by plant cells. However, most glucose is *converted into insoluble starch and stored*.
