Question
. Consider the following situation: A cell containing 300mM of NaCl is placed in a solution containing 200mM of urea and 400mM of glucose. Paying close attention to the units please answer the following questions: 6 points
a. Categorize the osmolarity of the extracellular solution.
b. Categorize the tonicity of the extracellular solution.
c. What is the net direction of water movement? Explain your answer
My answer:
a. hyperosmotic
b.hypotonic
c.into the cell - because the extracellular fluid is hypotonic to the intacellular so the direction of water movement will move into the cell?
Explanation / Answer
a.) The extracellular solution is hyperosmotic in nature since concentration of solutes is higher outside the cell.
b.) the tonicity of extracellular solution is hypotonic since a hypertonic solution has a higher concentration of solutes outside the cell than inside the cell.
c.) In an attempt to balance the concentrations of solutes inside and outside the cell, water will rush into the cell, and can cause it to burst.
c.)
