Question

Which of the following transport mechanisms utilizes energy? A) osmosis B) Diffusion Facilitated difusion D) endocytosis

Answer 1

D) Endocytosis is a transport mechanism that utilizes energy.
Endocytosis is an active transport, a biological process in which molecules from outside the cell (proteins for example) are passed through the cell membrane and put into the cell. This process requires energy.

The other transport mechanisms, osmosis, diffusion and facilitated diffusion are processes that do not utilize energy. 

Answer 2

Your answer will be D endocytosis.
