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.
Where does the carbon in glucose originally come from?
The carbon atoms in glucose come from the atmospheric carbon dioxide molecules that are taken in by plants for photosynthesis.
Where does the carbon and oxygen needed to make glucose come from?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
Is glucose a oxygen?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP….Aerobic vs anaerobic respiration.
| Aerobic | Anaerobic | |
|---|---|---|
| Reactants | Glucose and oxygen | Glucose |
When oxygen is present glucose is metabolized by?
Glycolysis
Glycolysis Overview Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that convert glucose into two molecules of pyruvate in the presence of oxygen or into two molecules of lactate in the absence of oxygen.
Do humans get carbon from glucose?
Glucose plus oxygen produces carbon dioxide, water and energy. When this process stops, the cell dies. The food and drink we eat can be broken into carbon compounds, one of the most simple being glucose (C6H12O6). When that reacts with oxygen (O2) in the cells, it produces carbon dioxide (CO2) and water (H2O).
Where do the 6 carbons of glucose come from?
Explanation: Glucose is formed through Photosynthesis by plants and some eukaryotas. During that process, 6 molecules of CO2 with 6 molecules of H2O are converted into 1 molecule of Glucose and 6 molecules of O2 .
What is the source of oxygen in glucose?
carbon dioxide
Thus, the oxygen in glucose comes from carbon dioxide from the atmosphere.
Does glucose have oxygen?
A single glucose molecule contains six oxygen atoms. The oxygen in glucose plays a vital role in aerobic respiration whereby glucose is oxidized to release energy (water and carbon dioxide are also byproducts of glucose oxidation).
How does oxygen break down glucose?
Aerobic respiration Glucose is oxidised to release its energy, which is then stored in ATP molecules. Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide. The carbon dioxide is a waste product of aerobic respiration because cells do not need it.
Where does oxygen in glucose and carbon dioxide come from?
By using the energy of sunlight, plants canconvert carbon dioxide and water intocarbohydrates and oxygen in a process calledphotosynthesis. As photosynthesis requiressunlight, this process only happens during theday. We often like to think of this as plants`breathing in carbon dioxide and `breathing outoxygen.
Where does most of the mass of glucose come from?
Glucose is C6H12O6, and the carbon and some oxygen in that equation come from Carbon Dioxide in the plants enviroment. Where does most of the mass of glucose come from? Carbon dioxide (CO^2) When a plant forms glucose molecules what is the source of carbon atoms? The carbon atoms come from the carbon dioxide it absorbs to perform photosynthesis
What happens to glucose and oxygen when the cell dies?
Where does a plant get the hydrogen it needs to make glucose?
When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air. Carbon dioxide doesn’t have any hydrogen in it, though, so the plant must use another source for hydrogen.
