Most sports drinks contain both carbohydrates and salts. The carbohydrates replace glucose burned during exercise and the salts replace salts lost in sweat. The salt also helps the small intestine absorb glucose. Pick the answer that accurately describes which salt is most beneficial for glucose absorption. A. NaCl, because Na+ is needed for glucose entry. B. HCl, because H+ is needed for glucose entry. C. KCl, because Cl– is needed for glucose entry. D. KCl, because K+ is needed for glucose entry.

NaCl, because Na+is needed for glucose entry.

Explanation:

NaCl is the most beneficial for glucose absorption because of the action of the Sodium- Potassium ATPase, which is an enzyme that facilitates the adsorption of glucose into the cells.

It functions with the aid of energy by binding with the glucose or ATP and 3 ions of sodium. The ATP is hydrolyzed leading to the phosphorylation of the pump creating a conformational change of the pump. The ATP is deposited into the cells and Na+ released to the outside as K+ attach to the pump for dephosphorylation to take place. The cycle continues.

really dont know just need some points

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
