Correct answer:
2
A process that involves the usage of ATP and glucose is glycolysis, which produces 2 pyruvates, 2 net ATP and 2 NADH molecules.

Pyruvic acid is created during glycolysis.
The first three-carbon compound produced in glycolysis is glyceraldehyde-3-phosphate (G3P) from the six-carbon glucose molecule. This occurs after the glucose molecule is broken down into two molecules of pyruvate.
Glycolysis itself does not output CO2. Just after glycolysis the 2 pyruvates which are derived from the glucose molecule during glycolysis, are converted into 2 acetyl CoA in the process of which one CO2 per pyruvate is released.After that the 2 acetyl CoA's enter the Kerbs cycle and a further 2 CO2's are produced for each.In total 6 CO2's are created after glycolysis2 during the conversion of pyruvates to Acetyl CoA4 Durint the TCA/ Citric Acid/ Kerbs Cycle
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.
When one six-carbon molecule of glucose is oxidized through glycolysis, it is converted into two molecules of pyruvate, each containing three carbons. This process also produces a net gain of two ATP molecules and two NADH molecules, which are used in cellular respiration to generate additional ATP in later stages. Glycolysis occurs in the cytoplasm and is the first step in the breakdown of glucose for energy.
While 2 net ATP are created in glycolysis, there also is a requirement of 2 ATP initially for glycolysis to take place
The 3 carbon molecule created from pGAL in glycolysis which is also produced in the Calvin cyclein photosynthesis.
Glycolysis results in a net gain of 2 ATP. Aerobic respiration results in 36 - 38 ATP.
