About this document
Cellular Transport Mechanisms Explained by Portia Egken is a document available to read on EtoBox.
Cellular transport occurs through passive and active mechanisms. Passive transport includes diffusion, facilitated diffusion, and osmosis, which move substances across membranes down their concentration gradients without energy expenditure. Active transport requires energy and includes protein pumps that move substances against their gradients, such as pumping ions out of cells. Bulk transport of large molecules occurs through endocytosis, which transports substances into cells, and exocytosis, which transp
