The cell regulates most molecules that pass through what cell structure?

Correct Answer: cell membrane
protective wall
plasma
ribosome

Explanation: The cell regulates most molecules that pass through the cell membrane. If a molecule is charged or very big, it won't make it through the cell membrane on its own. However, small, non-charged molecules like oxygen, carbon dioxide, and water, can pass through the cell membrane freely.
