Chambers A and B are placed next to each other, but are separated by a film similar to a cell membrane. Chamber A contains 80% c
arbon dioxide and Chamber B contains 20% carbon dioxide. Which of the following will occur? a. All of the carbon dioxide will move into Chamber B.
b. Some carbon dioxide will move from chamber A to chamber B.
c. All of the carbon dioxide will move into chamber A.
d. Some carbon dioxide will move from chamber B to chamber A.
e. There will be no net movement of carbon dioxide molecules
b. Some carbon dioxide will move from chamber A to chamber B.
Explanation:
The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
