WGU C107 Module 4 The Cell| Exam Questions with Correct Answers| Latest
Update 100% Solved
Which of the following is responsible for preventing polar molecules from passing through the
cell membrane? Phospholipid
In human cells, why is cholesterol is important? It increases the number of unsaturated fatty
acids necessary for normal fluidity.
Which type of membrane protein forms channels or pores to help molecules pass through it?
Integral
Which type of membrane protein allows for other cells to identify a cell? Glycoprotein
Which of the following describes diffusion? Solutes moving down their concentration
gradient.
Which of the following substance would most likely move across the cell membrane via simple
diffusion, assuming there were not protein channels in the membrane? Small lipids
Which of the following statements is NOT accurate about facilitated diffusion? It utilizes
energy from ATP to move molecules up their concentration gradients.
The process of moving impermeable molecules across a membrane (down their concentration
gradients) using channels or pores is referred to as: Facilitated diffusion
Which correctly describes what occurs when a cell is placed in a hypotonic solution? The cell
will increase in size as water enters through osmosis.
