Active transport requires energy and membrane proteins in order to function correctly.
The type of transportation known as "active" requires an energy input to operate.
Active transport involves the movement of chemicals from a low-concentration location to a high-concentration area in opposition to the concentration gradient. Being "active" means that this process uses energy (usually in the form of ATP). Passive transport is in opposition to it.
In contrast to passive transport, active transport involves the cell using energy (such as ATP) to move a chemical away from its concentration gradient.
In actuality, cells use a large portion of the energy they store in metabolism to maintain their active transport mechanisms.
Thus energy and membrane proteins are needed for active transport to function properly .
