How is glucose formed in the Calvin cycle?
Glucose actually isn't really formed in the Calvin Cycle. The product of the cycle is glyceraldehyde-3-phosphate. This might look familiar - it is. This is the intermediate in glycolysis after the 6 carbon sugar splits into 3 carbon chunks. After the Calvin Cycle glyceraldehyde-3-phosphate can be used directly as an immediate source of energy, or it can be modefied to become glucose (and then possibly paired to form sucrose for transport in the plant and then joined even more to make starch for storage in roots).

Which molecules are produced in the light reactions and then used in the Calvin cycle?
What happens to the 6 carbon molecule produced early in the Calvin Cycle?
Does photosynthesis use energy from ATP and high energy electrons from nadph produced in the light-dependent reactions to make glucose in the Calvin cycle?
Close, but no cigar! All was correct until you got to the product of the Calvin cycle. Glyceraldehyde-3-phosphate is the actual 3 carbon product of the Calvin cycle and from this, outside the Calvin cycle, many products can be made and glucose is one of them. So you see this..., 6CO2 + 6H2O --> C6H12O6 + 6O2 the equation of photosynthesis is slightly misleading. Google Calvin cycle pics. Naturally, ATP and NADPH do contribute their energy to that Calvin cycle.

Why are six carbon dioxide molecules required to make one glucose molecule?
What are the differences between the Calvin cycle and the Citric acid cycle?
The six carbon sugar in the Calvin cycle (Light Independent cycle) is split to form two three carbon sugars called phosphoglyceric acid (PGA) which is then turned into two phosphoglyceraldehyde's. These are then turned into glucose to be used at a later time. In other words, the Calvin cycle uses ATP and NADPH to make glucose while the Citric acid cycle (Krebs cycle) uses NADH, positive hydrogen ions and ADP to make succinic acid, ATP and NADH.

What is the Calvin cycle?
The Calvin cycle is the dark reaction in plants, that results in formation of the glucose molecule. The Calvin Cycle synthesizes G3P Basically, Photosynthesis is divided up into the Light reactions and the Calvin Cycle. The "photo" part is the light reaction part, and the "synthesis" is the Calvin Cycle. The Calvin Cycle's whole existence is to produce sugar. It does this with incorporating CO2 to eventually produce G3P, a sugar that can go on to make glucose etc... The Calvin cycle is powered by NADPH and ATP, which come from the light reactions. Of course this is a simplified version, as there are a number of intermediate molecules, but the idea is the same.For more info I would recommend reading Campbell and Reece (6th ed, 2005)
