Question

A type of transport protein found in the plasma membrane of cells lining the inside of the intestine allows sodium ions to diffuse down their concentration gradient. The ions move through the transport protein, and into the cell. These transport proteins will use the kinetic energy of the diffusing sodium ions to bring glucose into the cells as well. This transport protein would best be described as
a. Stopping the activity of the sodium potassium pump.
b. Increasing the concentration of glucose outside of the cell.
c. Lowering the energy of activation.
d. Increasing the number of digestive enzymes in the digestive tract.

Answer 1

Answer:

The transport protein would best be described as the activity of the sodium potassium pump. However, none of the alternatives are correct.  

Explanation:

Letter A: stopping the activity of the sodium potassium pump is incorrect because, it is the only mechanism of transport our organism has to move proteins into the cell. So, if we stop it or inhibit the sodium potassium pump, we will cause damage into the heart and intestine cells.

Letter B: Increasing the concentration of glucose outside of the cell is incorrect because, on normal conditions the glucose tends to outflow the cell, so the correct answer would be reduce the concentration of glucose outside of the cell, so that the amount of the glucose remain inside of the cell.

Letter C: lowering the energy of activation has nothing to do with this process at all.

Letter D: Increasing the number of digestive enzymes does not have anything to do with this process neither.

The letter A could be the write answer, if could delete the word stopping.
