Question

8/29 cfu - cells, cell membrane and transport (l)
a type of cellular transport is shown.
which description best identifies this type of cellular transport?
active transport, because energy is being used to move molecules against the concentration gradient
facilitated diffusion, because energy is being used to move molecules with the concentration gradient
osmosis, because energy is not being used to move molecules with the concentration gradient
endocytosis, because energy is not being used to move molecules against the concentration gradient

Explanation:

Active transport requires energy (ATP shown in the image) and moves molecules against the concentration gradient. Facilitated diffusion doesn't use energy for movement with the gradient. Osmosis is the diffusion of water and doesn't use energy. Endocytosis involves engulfing substances and isn't what's depicted here.

Answer:

Active transport, because energy is being used to move molecules against the concentration gradient
