ATP is produced in the mitochondria through processes such as cellular respiration. The mitochondrion is surrounded by an inner and an outer membrane. When ATP is generated in the mitochondria, it must travel to the cytoplasm where it is utilized for various cellular processes.

To move from the inner mitochondrial space to the cytoplasm, ATP must first pass through the inner mitochondrial membrane and then through the outer mitochondrial membrane. The inner mitochondrial membrane separates the mitochondrial matrix from the intermembrane space, while the outer membrane separates the intermembrane space from the cytosol, which is the fluid inside the cell.

Thus, as ATP moves from the mitochondrion (where it is produced) to the cytoplasm (where it is used), it traverses two membranes: the inner and the outer. This correctly supports the answer that ATP passes through two membranes during its transit from the mitochondrion to the cytoplasm.
