Moving Cellular Material

Question 12 • Anatomy & Physiology A

Which is true about both endocytosis and exocytosis? Check all that apply.

Answer
A
They use vesicles for cell transport.
B
They require energy for cell transport.
C
They remove wastes from the cell.
D
They move small, fat-soluble substances.

Explanation

Both processes use membrane-bound vesicles to move materials into or out of the cell. They also require energy, so both are forms of active transport. Endocytosis brings materials into the cell, while exocytosis releases materials outside it, so they do not both remove wastes. Small, fat-soluble substances can usually pass directly through the membrane rather than being transported this way.
