Plasma membrane; Membrane Transport -- Facilitated Diffusion Certain molecules use facilitated diffusion to cross the plasma membrane. Part A - Vocabulary review The sugar molecules produced by photosynthesis can be made into other molecules or broken down for energy. exocytosis. a) entropy has decreased Water, an unusual case for transport across the plasma membrane. Drag the terms to the appropriate locations on the concept map. The target molecule binds to the gated carrier protein and, in response, the carrier protein opens up - this allows the target molecule to enter. In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Facilitated diffusion doesn't require energy from the cell, so it's also a form of passive transport.

Molecules can move through the cells cytosol by diffusion, and some molecules also diffuse across the plasma membrane (as shown in the picture above). Some channel proteins are open all the time, but others are gated, meaning that the channel can open or close in response to a particular signal (like an electrical signal or the binding of a molecule).
