Explain: Passive Symports and Antiports.
$ \Rightarrow $ Some carrier or transport proteins allow diffusion only if two types of molecules move together.
$ \Rightarrow $ Symport: In a symport, both molecules cross the membrane in the same direction.
$ \Rightarrow $ Antiport: In an antiport, molecules move in opposite directions.
$ \Rightarrow $ Uniport: When a molecule moves across a membrane independent of other molecules, the process is called uniport.

$I.$ Carrier proteins are needed by both facilitated diffusion and active transport and are sensitive to inhibitors that react with protein side chains.
$II.$ Different types of proteins present in the membrane play a major role in both active as well as passive transport.
$III.$ The carrier proteins needed by facilitated and active transport are specific.
$IV.$ There is no need of energy to pump molecules against a concentration gradient in active transport.
$V.$ Transport rate reaches a saturation point when all the active proteins are used.
