Difficulty

Question 1

Which of the following is a reason why smaller molecules, such as oxygen, typically diffuse faster than larger molecules, such as glucose, through a medium?

Question 2

Question

Which of the following structural adaptations specifically facilitates faster diffusion by minimizing the diffusion distance?

Question 3

A diagram showing two chambers, A and B, separated by a permeable membrane. Chamber A contains a high concentration of solute particles, while Chamber B contains a low concentration of the same solute particles.

Based on the diagram, in which direction will the net movement of solute occur?

Question 4

The __________ prevent backflow of blood from the ventricles into the atria. As a system approaches equilibrium, the rate of net diffusion __________ because the difference in concentration between two areas decreases.

Question 5

Which of the following best explains why diffusion does not require an input of ATP from the cell?

Question 6

Under which set of conditions would the rate of diffusion for a specific molecule be the highest?

Question 7

Capillary walls are often only one cell thick, measuring approximately $1\text{ }\mu\text{m}$ in width. This adaptation facilitates rapid gas exchange by:

Question 8

Which statement best describes the movement of individual particles during the process of diffusion?

Question 9

The time required for diffusion to move substances across a space increases __________ as the distance between the two areas increases.

Question 10

Which of the following explains why diffusion is considered to be a passive process?
