Which of the following statements is true?

A. Endocytosis and exocytosis are passive transport mechanisms.
B. Unlike endocytosis, exocytosis does not rely on protein interactions with the plasma membranes.
C. During exocytosis, substances from inside the cell are moved outside.
D. Exocytosis involves infolding of the plasma membrane.

C) During exocytosis, substances from inside the cell are moved outside

Explanation:

A) Endocytosis and exocytosis are active transport mechanisms.

B) Exocytosis also relies on protein interaction with plasma membrane.

C) Exocytosis is process by which substances from inside the cell are moved outside and during endocytosis the substances from outside are moved inside.

D) Endocytosis requires the inflolding of plasma membrane.

Option C. During exocytoiss, substances moved from inside the cell are moved outside.

Explanation:

Exocytosis is the process of moving substances from inside (interior) the cell to the outside (exterior) of the cell. This process requires energy and is therefore a type of active transport. Unlike endocytosis, exocytosis does not rely on protein interactions with the plasma membranes. In exocytosis, membrane-bound vesicles containing cellular molecules are transported to the cell membrane. The vesicles join with the cell membrane and depose their contents to the exterior of the cell
