(A) In the Calvin cycle,the synthesis of one molecule of glucose $(C_6H_{12}O_6)$ requires $6$ turns of the cycle.Each turn of the Calvin cycle involves the fixation of one molecule of $CO_2$.For every $CO_2$ molecule fixed,$3$ $ATP$ and $2$ $NADPH$ are consumed in the reduction and regeneration phases.Specifically,in the regeneration phase of $RuBP$,$1$ $ATP$ is consumed per $CO_2$ molecule fixed.Since $6$ molecules of $CO_2$ are required to produce $1$ molecule of glucose,the total $ATP$ required for the regeneration phase is $6 	imes 1 = 6$ $ATP$ molecules.

During the synthesis of one molecule of glucose,how many molecules of $ATP$ are required for the regeneration phase of $RuBP$?
