An Artificial Cell Consisting of an Aqueous Solution Enclosed in a Selectively

question 67

Essay

An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose.

(A)Draw solid arrows to indicate the net movement of solutes into and/or out of the cell.
(B)Is the solution outside the cell isotonic, hypotonic, or hypertonic?
(C)Draw a dashed arrow to show the net osmotic movement of water, if any.
(D)Will the artificial cell become more flaccid, more turgid, or stay the same?
(E)Eventually, will the two solutions have the same or different solute concentrations?

Definitions:

Anti-Roll Bars

Components of a vehicle's suspension system designed to reduce body roll during sharp turns or irregular road conditions, enhancing stability.

Excessive Camber

When a vehicle's wheel tilt either inward or outward too much, leading to uneven tire wear and potential steering issues.

Excessive Caster

A condition in the alignment of vehicle wheels where the caster angle is beyond the recommended specification, affecting steering and stability.

Underinflation

The condition where a tire contains less than the recommended amount of air pressure, negatively affecting performance and safety.
