Answer:

As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.

Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.

Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.

Answer:

Read below

Explanation:

As a rule, molecules can either pass within the cell without applying energy throughout the process of passive transport (Molecules of oxygen for example). The molecules that are big and un-polar are unable to pass through the cell membrane easily. These molecules will need the energy to have the ability to go through the cell membrane. These molecules possibly might go through with the assistance of the carrier or facilitated proteins (Molecules of glucose for example).
