yes it does, the RuBP starts the Calvin Cycle.... it begins there
yes it does... The rest of the ATP (energy) is used to do this.

RuBP
RuBP stands for ribulose-1,5-bisphosphate, which is a molecule involved in the Calvin cycle of photosynthesis. It is a 5-carbon sugar that plays a key role in capturing carbon dioxide from the atmosphere to be converted into glucose.

RuBP
In the Calvin Cycle 3 ATP molecules are required to regenerate RUBP from 5 G3P. RuBP is an addition of CO2 that is involved with carbon fixation.
The Calvin Benson cycle uses ATP (adenosine triphosphate), NADPH (Nicotinamide adenine dinucleotide phosphate), and CO2 (carbon dioxide) to create glucose.
The end product of the Calvin cycle is a three-carbon sugar molecule called glyceraldehyde-3-phosphate (G3P). This molecule can be used to produce glucose and other carbohydrates, which serve as a source of energy for the plant.

The carbon dioxide acceptor in the Calvin-Benson cycle is ribulose-1,5-bisphosphate (RuBP). RuBP is a 5-carbon compound that combines with carbon dioxide in the first step of the cycle to form an unstable 6-carbon compound, which eventually leads to the production of glucose.

Carbon dioxide and RuBP combine to make PGA
