Question 11

Which of the following is a correct description of passive transport across biological membranes?

Accepted Answer

Movement of molecules down their concentration gradient without energy input

Question 12

Which of the following best explains the difference between carrier-mediated transport and vesicular transport?

Accepted Answer

Carrier-mediated transport involves proteins that change shape to move substances, while vesicular transport uses membrane-bound vesicles.
