The carbon to form glucose in photosynthesis comes from CO 2 in the atmosphere. After the light reactions store energy in the form of ATP and NADPH, the Calvin cycle uses that energy in a multiphase process to form G3P (a pseudo-sugar) which goes on to become glucose.
The chemical formula of glucose is C6H12O6.
C6H12O6
(6 atoms of carbon + 6 atoms of hydrogen + 6 atoms of oxygen)
Glucose is its own molecule. It is the simplest sugar molecule and is used as a a monomer for other more complex sugars.
CO2 (Carbon Dioxide)
C6 H12 O6 being the molecular formula of glucose, the carbon atoms are 6 in one molecule of glucose.
It is dependent on what happens to the Hydrogen atoms.
The molecular formula for Fructose is C6H12O6. This indicates that there are six carbon atoms, twelve hydrogen atoms, and six oxygen atoms.
12 carbon atoms exist in a molecule of maltose if the molecules have 12 oxygen atoms.
Glucose contains six carbon atoms, whereas pyruvate only contains three, so it is possible to derive two pyruvate molecules (3+3 carbon atoms) from one glucose molecule (=6 carbon atoms). During the early stages of glycolysis, the glucose is converted into Fructose-1,6-bisphosphate. This molecule also has six carbon atoms, and is split by an enzyme called 'fructose biphosphate aldolase' into two separate molecules containing three carbon atoms: glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. It is the glyceraldehyde-3-phosphate that is later converted into pyruvate, accounting for the first pyruvate molecules from glucose. However, the other 3-carbon molecule, dihydroxyacetone phosphate, is kept in equilibium with glyceraldehyde-3-phosphate by an enzyme known as 'triose phosphate isomerase', so that this is eventually converted into pyruvate as well. The result being two pyruvate molecules per glucose molecule.
The formula for glucose is C6H12O6. This means that six carbon atoms can be found within one molecule of glucose, as well as twelve hydrogens and six oxygens. In, for example, photosynthesis, carbon dioxide is involved in a complex series of reactions that form glucose from those molecules, as well as from hydrogen atoms from water. If 54 molecules of carbon dioxide, and thus 54 atoms of carbon, were used in photosynthesis, nine molecules of glucose would be formed, thus meaning that all of the carbon atoms would become glucose. Therefore, all of the carbon atoms can potentially become part of glucose.
19.86 x 1019 carbon atoms (just times it by 6, the number of carbon atoms in one glucose molecule)

18 carbon atoms (6 in each)
The Carbon in Glucose made by plants comes from the Carbon in the Carbon Dioxide (CO2) gas in the air.
Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.
18 carbon atoms
Once molecule of glucose contains 6 atoms of carbon, 12 atoms of hydrogen and 6 atoms of oxygen.
Twelve. Glucose is C6H12O6, so two molecules of glucose would give you: 12 carbon atoms 24 hydrogen atoms 12 oxygen atoms The 12 molecules of oxygen would give 24 oxygen atoms, for 48 total atoms of oxygen. So...each carbon atom would take two oxygen atoms to give 12 molecules of carbon dioxide, and each remaining oxygen atom would take two hydrogen atoms to give 12 molecules of water.
