CELL MEMBRANE STRUCTURE EXAM QUESTIONS AND ANSWERS
UPDATED 2024/2025 ALL ANSWERS 100% CORRECT DETAILED BEST
GRADED A+ FOR SUCCESS
channel proteins - CORRECT ANSWERS proteins that provide passageways through the
membrane for certain hydrophilic (water-soluble) substances such as polar and charged
molecules
cell recognition proteins - CORRECT ANSWERS Glycoprotein that helps the body defend
itself against pathogens.
enzymatic proteins - CORRECT ANSWERS accelerate the speed of chemical reactions
glycoprotein - CORRECT ANSWERS short sugar chains attached to proteins
glycolipids - CORRECT ANSWERS Membrane carbohydrates that are covalently bonded to
lipids.
passive trasport - CORRECT ANSWERS the movement of dissolved materials across a cell
membrane without using cellular energy.
simple diffusion - CORRECT ANSWERS Simple diffusion is the net passive movement of
molecules/particles through the cell membrane from higher concentration to a lower
concentration of that molecules/particles until equilibrium has been achieved in both sides
active trasport - CORRECT ANSWERS Movement of substances across the plasma
membrane that requires energy
facilitated diffusion - CORRECT ANSWERS A process in which substances are transported
across a plasma membrane with the concentration gradient with the aid of carrier (transport)
proteins; does not require the use of energy.
