Question

match the description of transport protein or transport type to the image. passive carrier proteins facilitated diffusion active carrier proteins active transport

Explanation:

Passive carrier proteins are involved in facilitated diffusion which is a passive - transport process where molecules move down their concentration gradient with the help of a carrier protein. Active carrier proteins are used in active transport which requires energy (as indicated by the 'Energy' label in the image) to move molecules against their concentration gradient. The left - most image shows molecules moving down their gradient with a carrier protein (facilitated diffusion with passive carrier proteins). The right - most image shows molecules moving against their gradient with energy input (active transport with active carrier proteins).

Answer:

From left to right: Passive carrier proteins and facilitated diffusion, Active carrier proteins and active transport
