Question
Chapter 5, Problem 8RQ
Summary Introduction
To explain:
The change in contents of compartment B when in compartment A and B containing glucose solution separated by permeable membrane more glucose is added to compartment A.
Introduction:
A solution is made up of both “solute and solvent”. The solute is usually a solid and solvent is usually liquid. When the concentration of solute and solvent is equal in and out of the cell, it is said to be in an equilibrium condition. If the concentration of both solute and solvent is unequal like in hypo or hypertonic solutions, a cell will always equalize the concentration of both solute and solvent inside and outside the cell membrane by osmosis.

- If two solutions separated by a semi-permeable membrane are isotonic, can you conclude that they are in chemical equilibrium?arrow_forwardThe transport of a molecule is investigated using two chambers (left and right) separated by a synthetic membrane containing transport proteins. A solution containing varying concentrations of the molecule is added to the left side while pure water is added to the right. The transport rate of the molecule is determined by measuring the concentration of molecule that accumulates on the right side. The following table summarizes the transport rate of the molecule at various concentrations. Based on this you can conclude: a) the molecule is most likely transported by facilitated diffusion b) the molecule is moving across the membrane by passive transport c) the membrane is freely permeable to the molecule d) the molecule is most likely transported by active transportarrow_forwardA phospholipid bilayer with equal amounts of saturated and unsaturated fatty acids displays a specific permeability to glucose.
