Detailed explanation-1: -Regeneration. One G3P molecule leaves the cycle and will go towards making glucose, while five G3Ps must be recycled to regenerate the RuBP acceptor.

Detailed explanation-2: -One of the three-carbon molecules of G3P leaves the cycle to become a part of a carbohydrate molecule. The remaining G3P molecules stay in the cycle to be formed back into RuBP, which is ready to react with more CO2.

Detailed explanation-3: -Stage 3: Regeneration One is exported while the remaining five G3P molecules remain in the cycle and are used to regenerate RuBP, which enables the system to prepare for more CO2 to be fixed.

Detailed explanation-4: -Formation of one molecule of glucose (6C) requires 6 turns of Calvin cycle as 3 turns of carbon fixation obtains net one molecule of glyceraldehyde 3 phosphate (G3P; 3C) and two molecules of G3P are required to make one molecule of 6 carbon glucose.
