A) (1pt) ATP hydrolysis is necessary for actin treadmilling. (4sentence max)
B) (1pt) Late endosomes are converted to mature lysosomes by anincrease in their internal pH. (4 sentence max)
C) (1pt) Lysosomal membranes contain a proton pump that utilizesthe energy of ATP hydrolysis to pump protons out of the lysosome,thereby maintaining the lumen at a low pH. (4 sentence max)
D) (1pt) If cells were treated with a weak base whichneutralizes the pH of organelles, it is expected that M6P receptorswould accumulate in the Golgi due to the M6P receptors inability tobind lysosomal enzymes. (4 sentence max)
