A large molecule needs to enter the cell and does so via a protein channel. This requires the expenditure of energy on the cell's part. Which type of transport would this be considered?

Active transport

Explanation:

The type of transport that would be considered is active transport.

Active transport is a type of transport that involves the movement of molecules or ions across the membrane through the use of energy. Most of the time, the movement of the ion or molecule is usually from the region of lower concentration to the region of higher concentration.  Examples of active transport include the sodium-potassium pump, exocytosis, and endocytosis.
