Which of these is responsible for establishing the concentration gradient needed for the selective reabsorption of glucose and amino acids?
|
|
co transporter protein
|
|
|
osmotic gradient
|
|
|
sodium-potassium pump
|
|
|
sodium-calcium pump
|
Explanation:
Detailed explanation-1: -This work is done by the Na+/K+ ATPase pump, which pumps 3 Na+ ions out of the cell and 2K+ into the cell to generate the Na+ and K+ concentration gradient.
Detailed explanation-2: -The final mechanism for maintaining the concentration gradient involves active transport of sodium and potassium ions via the sodium-potassium pump. The sodium-potassium pump ejects three sodium ions for every two potassium ions pumped into the cell; energy is needed for this process.
