Question

Which of the following mineral is needed for amino acid to pass into the bloodstream?

• A. Potasium
• B. Sodium
• C. Iron
• D. Both A and B

Answer 1

The correct option is D Both A and B

Amino acids constitute the proteins. They are absorbed in the blood by active transportation using sodium-potassium amino acid transporter. They use ATP in the process and transported from the lumen to the cells against the gradient.

So the correct answer is 'Both A and B'.
