Define uniport,symport and antiport. Do they require energy?

Uniport,symport,and antiport are types of facilitated diffusion mediated by carrier proteins.
$1$. Uniport: In this process,a molecule moves across a membrane independent of other molecules.
$2$. Symport: In this process,two types of molecules cross the membrane simultaneously in the same direction.
$3$. Antiport: In this process,two types of molecules move in opposite directions across the membrane.
Energy requirement: These processes are types of facilitated diffusion,which is a passive transport mechanism. Therefore,they do not require energy $(ATP)$ to move molecules across the membrane.
