Best Answer: Active transport is the mediated process of moving particles across a biological membrane against a concentration gradient. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed primary active transport. Secondary active transport involves the use of an electrochemical gradient.
Â· just now. Report Abuse. the answer is B-exocytosis Active Transport has to do with using energy to transport molecules and occurs through channels, not vesicles. Phagocytosis and endocytosis are vesicle mediated transport directed into a cell.Source(s): I'm an Immunologist.eport Abuse. B) Exocytosis. Exocytosis is the release of the contents of a cell vacuole to the exterior. It can't be active transport because active transport refers to the cell taking substances in.
