Glaxo Smith Kline (GSK) in Research Triangle Park has hired a recent biology graduate to explore a drug that would inactive membrane transport proteins in the plasma membrane. The recent graduate discovered a chemical that inactivated all membrane transport proteins. Wich of the following molecule (s) would not be able to get into a cell treated with this chemical?

a. testosterone

b. CO2

c. K+

d. glucose

Glucose would not be able to get into the cell treated with this chemical

Potassium mwill not be able to move or transport may be affected

Explanation:

As all membrane transport proteins are inactivated glucose is abig molecule it cannot pass without transporter protein.

Potassium transport is through sodium potassium pump and leak channels. As all transport protein are affected so it should not be able to move but if drug does not affect them then they will be unaffected.
