Question

which ones are channels, carriers, and which ones refer to both? a) provide a continuous path across the membrane b) undergo a change in shape to transport solutes across the membrane c) allow water molecules and small ions to flow quickly across the membrane d) provide a hydrophilic path across the membrane e) transport primarily small polar organic molecules f) transport solutes down a concentration or electrochemical gradient g) are integral membrane proteins which ones are channels, carriers, and which ones refer to both? a) provide a continuous path across the membrane b) undergo a change in shape to transport solutes across the membrane c) allow water molecules and small ions to flow quickly across the membrane d) provide a hydrophilic path across the membrane e) transport primarily small polar organic molecules f) transport solutes down a concentration or electrochemical gradient g) are integral membrane proteins

Explanation / Answer

a) Provide a continuous path across the membrane - channelb) Undergo a change in shape to transport solutes across the membrane - carrier c) Allow water molecules and small ions to flow quickly across the membrane - channel d) Provide a hydrophilic path across the membrane - both channel and carrierse) Transport primarily small polar organic molecules - carriers f) Transport solutes down a concentration or electrochemical gradient
