passive transport  Transport Without Energy Expenditure By The Cell Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell  Significance of Passive Transport · It commonly occurs in the blood-brain barrier as specific molecules, such as sodium thiopental, can diffuse

Passive Transport · Passive transport is the net movement of molecules from a high concentration to a low concentration without the requirement for energy from Active transport helps in the uphill movement of substances On the other hand, passive transport helps in the downward movement of substances
