A is the answer. It’s like addition.
I believe the answer is the Regeneration stage.
A this stage of the Calvin Cycle, only one of the G3P molecules leaves the cycle and is sent to the cytoplasm to contribute to the formation of other compounds needed by the plant. Because the G3P exported from the chloroplast has three carbon atoms, it takes three "turns" of the Calvin cycle to fix enough net carbon to export one G3P. Each turn makes two G3Ps, therefore three turns make six G3Ps.
Its made up of microtubules, microfilaments and intermediate filaments. They give the cell shape and organize its parts
The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.
The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.
Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.
