Transport of molecules across a membrane can be active or passive. Active transport requires energy expenditure, as it transfers the molecules against their concentration gradient. In passive transport, the transfer of molecules takes place along their concentration gradient. So, energy is not required in this process. The two types of membrane transport proteins are channel and carrier proteins.
