Pinocytosis is the process in which the cell:
A
Nonspecifically internalizes extracellular fluid and dissolved solutes via small endocytic vesicles
B
Directly transports ions across the plasma membrane through ATP-powered pumps without vesicle formation
C
Exports cytosolic proteins to the extracellular space by fusion of secretory vesicles with the plasma membrane
D
Engulfs large particles such as bacteria using actin-driven pseudopods to form a phagosome
