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
