Question

match the description of transport protein or transport type to the image. passive carrier proteins facilitated diffusion active carrier proteins active transport drag each item above to its appropriate location in the image. note that every item may not have a match, while some items may have more than one match.

Explanation:

Passive carrier proteins are involved in facilitated diffusion which is a passive - transport process (no energy required) where molecules move down their concentration gradient with the help of a carrier protein. Active carrier proteins are involved in active transport, which requires energy (usually ATP) to move molecules against their concentration gradient. In the left - most image, the green molecules are moving down their concentration gradient with the help of a blue carrier protein, which is facilitated diffusion and involves passive carrier proteins. In the right - most image, the blue molecules are moving against their concentration gradient and energy is being used, so this is active transport involving active carrier proteins.

Answer:

• Left - most image: passive carrier proteins, facilitated diffusion
• Right - most image: active carrier proteins, active transport
