FSU BSC 2010 Chapter 7 Marie Dennis questions
with verified answers
active transport Ans✓✓✓ the movement of substances across a cell
membrane with the use of energy by the cell; goes against the
concentration gradient
aquaporins Ans✓✓✓ channel proteins that facilitate the passage of
water
carrier proteins Ans✓✓✓ a protein that transports substances across a
cell membrane
channel proteins Ans✓✓✓ provide corridors that allow a specific
molecule or ion to cross the membrane
cotransport Ans✓✓✓ occurs when active transport of a solute
indirectly drives transport of other substances
diffusion Ans✓✓✓ Movement of molecules from an area of higher
concentration to an area of lower concentration.
electrochemical gradient Ans✓✓✓ drives the diffusion of ions across a
membrane
