There are two forms of active uptake\/transport:<\/p>\n

1. Active Carrier Transport<\/p>\n

2. Endocytosis<\/p>\n

1. Active Carrier Transport<\/b><\/p>\n

Active carrier transport is similar to facilitated diffusion in that it utilizes a protein (carrier). However, energy is also used to move compounds against their concentration gradient. The following figure and video do a nice job of illustrating active carrier transport.<\/p>\n

Endocytosis is the engulfing of particles, or fluids, to be taken up into the cell. If a particle is endocytosed, this process is referred to as phagocytosis. If a fluid is endocytosed, this process is referred to as pinocytosis as shown below.<\/p>\n
