Passive transport doesn't require energy (ATP), active transport does require energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).Dec 2, 2008 read more
Active and passive transport are biological processes that move oxygen, water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. read more
The major difference between active and passive transport is that passive transport does not require the application of external energy, while active transport does. Both processes move molecules across the cell membrane, but passive transport always takes advantage of existing concentration gradients to allow a natural diffusion of molecules. read more
Types of active transport are endocytosis, exocytosis. Types of passive transport include, osmosis, diffusion. Anything soluble is transported by passive transport and particles like proteins, ions, large cells, sugars are transported by the process of active transport. read more
