This question has a mistake. Here is the correct question:
Which molecule can pass freely through the lipid bilayer
?
Answer:
The correct answer is Lipid-soluble molecules.
Explanation:
In order for a cell to survive, it must receive nutrients and oxygen from the outside that will be transported to them by means of a single cell.
For this to happen, each molecule must pass through a lipid bilayer which is responsible for forming membranes.
Not all molecules can achieve this, but only those that can dissolve in lipids and some small ones will get through this bilayer, leaving out large molecules and ions.
