In $C_3$-cycle,how many $\text{ATP}$ molecules are used for the formation of $3$ molecules of hexose (glucose) sugar?

The biosynthetic phase of photosynthesis includes ?
$(A)$ Use of $ATP$
$(B)$ Synthesis of $NADPH + H^{+}$
$(C)$ Formation of sugar
$(D)$ Release of oxygen
$(E)$ Reduction of $CO_2$

The primary site of the dark reaction of photosynthesis is ......... .

How many molecules of $ATP$ and $NADPH$ are required for every molecule of $CO_2$ fixed in the Calvin cycle?

$ATP$ and $NADH$ (or $NADPH$),which are synthesized in the photochemical reaction,are used in which phase?

Select the correct option for photosynthesis in $C_3$-plants.
