Active transport biology

A GIF by the Amoeba Sisters demonstrating active transport. www.amoebasisters.com/amoebagifs.html

Active transport is the energy-driven transportation of ions, small molecules, and solutes, divided into two types- Primary and Secondary active transport.

Mass transfer of materials through the cell membrane occurs by changes in the plasma membrane at localized sites. It involves 2 processes, endocytosis, and ...

Active transport relies on the use of energy to move substances into and out of cells. Usually, molecules are traveling against a concentration gradient.
