Answer: diffusion
Explanation:
Diffusion is the over all movement of molecules from one region where it is in high concentration to another another region where it is in lower concentration.
This movement continues until the concentration of both regions are equal. Smaller non polar molecules are able to diffuse through the lipid bilayer of the membrane .
Movement through the membrane is dependent on the concentration gradient, that is the difference in concentration between the two areas.
It is also dependent on the size of the molecule

A lipid molecule primarily is used as a storage mechanism for the cell as ATP doesn't last very long before degenerating.
Answer:
To turn sugars into energy
Explanation:
- Mitochondria are main sites of aerobic respiration. They are miniature biochemical factories where food stuffs are completely oxidised to carbon dioxide and water.
- The energy (ATP) produced in the mitochondria helps to perform various energy requiring processes.
- Because of the formation of ATP in mitochondria it is called power house of the cell.
- Photosynthesis: Light reaction (in thylakoids), Dark reaction (in stroma).
- Storage of starch.
