Vedclass · Answer

(C) Passive transport is the movement of molecules across a cell membrane without the expenditure of metabolic energy $(ATP)$.It occurs along the concentration gradient.The two primary mechanisms of passive transport are:$1$. Simple diffusion: The movement of molecules from a region of higher concentration to a region of lower concentration.$2$. Facilitated diffusion: The movement of molecules across the membrane with the help of special membrane proteins (carrier proteins or channel proteins) along the concentration gradient.Osmosis is a specific type of diffusion involving the movement of water molecules across a semi-permeable membrane,which is also a form of passive transport.However,in the context of general transport mechanisms across the cell membrane,passive transport is broadly categorized into simple and facilitated diffusion.
