Final answer:
Facilitated diffusion is NOT an example of active transport as it does not require energy; it's a passive transport process that uses protein channels to transport molecules across a membrane.
Step-by-step explanation:
The correct answer to the question "Which of the following is NOT an example of active transport?" is B) Facilitated diffusion. Active transport is the process by which cells move molecules across the cell membrane against the concentration gradient, using energy, typically in the form of ATP.
Examples of active transport include phagocytosis, pinocytosis, endocytosis, and exocytosis. Pinocytosis and phagocytosis are variations of endocytosis, where the cell membrane invaginates and forms a vesicle that engulfs extracellular material. Facilitated diffusion, in contrast, does not require cellular energy but uses protein channels to help move molecules from an area of higher concentration to an area of lower concentration.
