The subcellular structure that degrades proteins is called the: A. Tight junction B. Mitochondria C. Lysosome D. Plasma membrane E. Ribosome ANS: C 2. An experiment is done to measure the uptake of an a mino acid into a cell. The following data are obtained: If Na+ is removed from the extracellular bathing solution , or if a drug is added that prevents the cell from making adenosine triphosphat e (ATP), the uptake of amino acid into the cell is markedly reduced. According to thi s information, which of the following mechanisms is probably responsible for the transpor t of the amino acid into the cell? A. Passive diffusion through the lipid bilayer B. Uniporter C. Transport ATPase D. Na+ symporter E. Na+ antiporter ANS: D 3. A membrane permeable by only Na+ separates two compartments containing Na 2SO 4, shown as follows: ______________________________________________________________________________________________
