In the process of carbon fixation, three molecules of RuBP combine with three molecules of CO2 to produce three six-carbon molec
ules, which are then split to produce 6 molecules of 3-phosphoglycerate. After phosphorylation and reduction produce 6 glyceraldehyde 3-phosphate (G3P), what more needs to happen to complete the Calvin cycle
Calvin cycle also known as light independent stage is the second stage of the photosynthetic process. It occurs in the Stroma of the CHLOROPLAST. The Calvin cycle can be broken down to three major steps: carbon fixation, reduction and regeneration.
Carbon fixation as described in the question is when 3 molecules of RuBP (CO2 acceptor) combine with 3 molecules of CO2 to produce 3 six-carbon molecules, which are then split to produce 6 molecules of 3-phosphoglycerate (PGA). This fixation is catalyzed by RUBISCO enzyme.
The 6 molecules of PGA are then converted to 6 molecules of Glyceraldehyde-3-phosphate (G3P) by ATP and NADPH (from light stage) in a process called reduction.
After these initial two stages, one of the G3P molecules leave the cycle to contribute to the formation of organic food (glucose) while the remaining 5 G3P molecules are used to regenerate RUBP molecule in order for the cycle to commence all over again starting from fixation.
If the explosion doesn't alter the Earth's rotation, the lack of moon would cause the Earth to rotate at a constant speed. This means that every day would be 24 hours long for the rest of the Earth's existence. The Earth's tides would also change because the gravity the moon exerts on the oceans would no longer exist.
