C. the cell membrane.
the membrane let's things in and out of the cell.
A lipid molecule primarily is used as a storage mechanism for the cell as ATP doesn't last very long before degenerating.
Answer: Cellular transport independent of ATP like osmosis and difussion (Simple and facilitated).
Explanation: The animal affected has a mitochondrial disease that affects its capacity of ATP production, thus, the animal active transport will be afected since require ATP. On the contrary, the animal passive transport will be functional because its independent of ATP, like osmosis which is water transport in favor of concentration gradient and facilitated diffussion of small molecules.
