Questions and Answers
active process - Correct Answers -A process that involves the expenditure of energy
active transport - Correct Answers -requires energy to move substances
Bilayer - Correct Answers -two layers that make up a single membrane
carrier mediated transport - Correct Answers -transport of ions or molecules across a
cell membrane by special carrier proteins
carrier protein - Correct Answers -a protein that carries substances from one side of the
cell membrane to the other
cell membrane - Correct Answers -a membrane that forms the external boundary of a
cell
facilitated diffusion - Correct Answers -The process where
proteins allow the movement of substances through the cell membrane along the
concentration gradient
facilitated transport - Correct Answers -proteins in the cell membrane allow molecules to
be transported across the membrane
