Question

this section of the cell membrane illustrates one method of cellular transport. consider steps a, b, and c. what transport mechanism is represented?
oa osmosis
ob endocytosis
oc active transport
od facilitated diffusion

Explanation:

Osmosis is the movement of water molecules across a semi - permeable membrane. Endocytosis is the process of taking in substances by engulfing them with the cell membrane. Active transport moves substances against the concentration gradient using energy. Facilitated diffusion uses transport proteins to move substances down the concentration gradient without energy input. Based on the illustration of a transport protein being used to move substances across the membrane down the concentration gradient (as no energy input is indicated), it is facilitated diffusion.

Answer:

D. facilitated diffusion
