Question

a type of cellular transport is shown. which description best identifies this type of cellular transport? 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 facilitated diffusion, because energy is being used to move molecules with the concentration gradient active transport, because energy is being used to move molecules against the concentration gradient

Explanation:

Active transport uses energy (ATP shown in the image) to move molecules against their concentration gradient. Osmosis is the diffusion of water and doesn't use energy for solute - movement shown here. Endocytosis is a bulk - transport process and not applicable here. Facilitated diffusion moves molecules with the concentration gradient without energy expenditure.

Answer:

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