HELP PLEASEE Which type of membrane protein is correctly paired with its function?

A) channel protein; allows a specific molecule to pass

B) cell recognition proteins; attachment site for cytoskeleton

C.) receptor proteins: enzymes that initiate a reaction inside the cell

D) carrier proteins; transports water molecules with the concentration gradient

A) Channel Protein

Explanation:

Channel proteins span the membrane and make hydrophilic tunnels across it, allowing their target molecules to pass through by diffusion.

Channels are very selective and will accept only one type of molecule to transport

A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly.
