• Hexose Sugars are simple 6 carbon sugars
• An example of Hexose Sugar is glucose (C6H12O6)
• A molecule of hexose sugar is produced via the joining of two molecules of triose phosphate (TP) together
• Hexose sugars can be used in to form larger carbohydrates
• The Calvin Cycle needs to turn 6 times to produce one hexose sugar
• 3 turns of the cycles form 6 molecules of triose phosphate
• 5 out of 6 of these 6 molecules are used to regenerate the RuBP
• Therefore, for every 3 cycles, only one TP is produced that is required to form the hexose sugar. As the hexose sugar is 6 carbons long it requires 2 TP molecules
• 6 turns of the Calvin Cycle require 18 ATP and 12 reduced NADP from the light dependent reaction
• The reaction is slow and inefficient however it is this method to ensure that RuBP is always sufficient so that it can readily bind with CO2 taken from the atmosphere

Larger carbohydrates can be formed by the joining of multiple hexose sugars together
Lipids are produced by the synthesis of glycerol from triose phosphate and fatty acids which are synthesised from glycate 3 phosphate
Amino Acids:
Some of the amino acids used are produced from glycerate 3-phosphate
