A solution surrounding a cell is hypertonic if:
A) It contains the same amount of nonpenetrating solute particles as the interior of the cell
B) It contains more nonpenetrating solute particles than the interior of the cell
C) It contains fewer nonpenetrating solute particles than the anterior of the cell - answer ✔✔-B) It
contains more nonpenetrating solute particles than the interior of the cell
All of the following are true of the active transport except:
A) ATP is used to power the active transport
B) It uses a membrane-bound carrier protein
C) Solutes move along with their concentration gradient
D) Solutes move against their concentration gradient - answer ✔✔-C) Solutes move along with their
concentration gradient

True
Determine the correct order of solutes from smallest to largest - answer ✔✔-sodium chloride, urea,
glucose, albumin
Glucose can be transported by the facilitated diffusion in our cells. T/F - answer ✔✔-True
In normal conditions, inside the cell is more positive than outside the cell. T/F - answer ✔✔-False
, Osmosis requires ATP. T/F - answer ✔✔-False
The greatest amount of filtration takes place in? - answer ✔✔-Kidney
