Question

sort the phrases into the appropriate bins depending on whether they are true only for channels, true only for carrier proteins, or true for both channels and carriers. view available hint(s) are integral membrane proteins undergo a change in shape to transport solutes across the membrane provide a hydrophilic path across the membrane transport solutes down a concentration or electrochemical gradient allow water molecules and small ions to flow quickly across the membrane transport primarily small polar organic molecules only channels only carriers both channels and carriers provide a continuous path across the membrane

Explanation:

Channels are integral membrane proteins that provide a continuous hydrophilic path across the membrane, allowing water molecules and small ions to flow quickly across the membrane. Carrier proteins are also integral membrane proteins that transport solutes down a concentration or electrochemical gradient, and they undergo a change in shape to transport solutes across the membrane. They transport primarily small polar organic molecules.

Answer:

• only channels: provide a continuous path across the membrane, allow water molecules and small ions to flow quickly across the membrane
• only carriers: undergo a change in shape to transport solutes across the membrane, transport primarily small polar organic molecules
• both channels and carriers: are integral membrane proteins, provide a hydrophilic path across the membrane, transport solutes down a concentration or electrochemical gradient
