Question

which type of transport is shown below?
e. passive
f. active
g. osmosis
h. facilitated diffusion

Explanation:

Active transport requires energy (ATP) to move substances against their concentration gradient (from low to high concentration). In the diagram, ATP is shown, and the movement is from a lower number of particles (upper side) to a higher number (lower side), which is against the concentration gradient. Passive transport (like osmosis and facilitated diffusion) does not require ATP and moves substances down their concentration gradient.

Answer:

f. active
