CO2 + H20 ----> H2CO3 ----> H+ + HCO3
H+ + CO3- ----> H2CO3
H2CO3 ----> H2O + CO2
CO2 + H2O -----> 2H+ + CO3
Membrane permeable to CO2
Measurement is amperometric
Measurement is potentiometric
(a) and (c) are correct
None of the above
Ecell = Ecathode + Elj - Eanode
Ecell = Eanode - Elj - Ecathode
Ecell = Ecathode - Elj - Eanode
Ecell = Eanode + Elj - Ecathode
Reference and testing electrodes are assigned to different compartments closely linked
Reduction takes place at the anode
The testing electrode and reference are contained within a single unit
The calomel electrode is a good example of a combination electrode
Glass electrode which consists of silicon dioxide, sodium oxide, and aluminon oxide
Electrode surface consisting of a polypropylene membrane permeable to H+
Electrode surface consisting of a polypropylene membrane permeable to H2CO3/CO2
Glass electrode which is permeable to H+
The semipermeable membrane must be permeable to many ion species
A concentration gradient for a given charged ion species must exist across that membrane.
If a membrane is permeable to two different ion species, then the ion activity of both species can be measured.
The membrane potential across a semipermeable membrane must be constantly changing.
Concentration of potassium chloride filling solution
Surface area of the electrode
Activity of total anion in the paste covering electrode
Concentration of silver in the paste covering electrode
They can measure over a wider range of concentration
They are not subject to pseudohyponatremia caused by high lipids or high proteins
They do not require temperature equilibration
They require less maintenance
Zn ---> Zn 2+ + 2e-

Combines the techniques of zone electrophoresis, isotachophoresis, isoelectric focusing, and gel electrophoresis in small-bore fused silica capillary tubes.
Involves exposure of electrophoresed proteins to antisera against different immunoglobulin heavy and light chains with resultant precipitation.
Involves transfer of separated proteins to a strip of nitrocellulose by electroblotting followed by an immunochemical reaction with a specific antibody.
Uses electrophoresis in two dimensions to assess global changes in protein expresssion.

Increased migration rate of protein
Decreased migration rate of protein
No change in the rate of migration of protein
None of the above
There would be an increased alpha1-globulin band
There would be a decreased beta-globulin band
There would be an increase in the gamma globulin bands
A decreased alpha2-globulin band
It is inversely proportional to electrophoretic mobility
It is directly proportional to electrophoretic mobility
It is equal to the electrophoretic mobility
There is no relationship between net charge and electrophoretic mobility
Albumin values cannot be calculated using densitometry
