Which of the following is NOT a method or pathway of movement for substances traveling across a capillary wall?
A) diffusion through intercellular clefts
B) direct diffusion through the plasma membrane
C) transport via vesicles by endocytosis or exocytosis
D) active transport using proteins and ATP
E) diffusion through the pores of fenestrated capillaries

Question

Quizplus · Accepted Answer

Active transport using proteins and ATP is not a method or pathway of movement for substances traveling across a capillary wall. This is because active transport requires the use of energy and specific transport proteins to move substances against their concentration gradient, which is not typically necessary for substances crossing a capillary wall. The other options (A, B, C, and E) are all viable methods for substances to travel across a capillary wall, depending on factors such as molecule size and shape, membrane permeability, and concentration gradients.
