Carriers are membrane proteins that complement the structural features of the molecules transported. They bind to the chemicals in order to move them across the cell membrane. Energy is consumed because the transport proceeds against the concentration gradient.
1. A person or animal harboring a specific Infectious Agent in the absence of discernible clinical disease and which serves as a potential source of infection. The carrier state may occur in an individual with an infection that is inapparent throughout its course (known as a healthy or asymptomatic carrier) or the carrier state may exist only ...
The carrier proteins involved in facilitated diffusion simply provide hydrophilic molecules with a way to move down an existing concentration gradient (rather than acting as pumps). Channel and carrier proteins transport material at different rates.
