Select all that applyWhich of the following are ions that can be found only in trace amounts in the plasma?Multiple select question.K+Na+HCO3-Ca2+Mg2+Zn2+Cu2+Cl-
Solution
The ions that can be found only in trace amounts in the plasma are Zn2+ and Cu2+.
Here's why:
-
K+ (Potassium): This is a major ion in the body and is not only found in trace amounts. It plays a key role in heart function and muscle contraction.
-
Na+ (Sodium): This is another major ion in the body. It is essential for nerve and muscle function.
-
HCO3- (Bicarbonate): This ion is a significant component of the pH buffering system in the body.
-
Ca2+ (Calcium): This is a major ion in the body, necessary for muscle function, nerve function, and blood clotting.
-
Mg2+ (Magnesium): This is a major ion in the body, necessary for many biochemical reactions.
-
Zn2+ (Zinc): This ion is found in trace amounts in the body. It is necessary for the function of many enzymes.
-
Cu2+ (Copper): This ion is also found in trace amounts in the body. It is necessary for the function of many enzymes.
-
Cl- (Chloride): This is a major ion in the body. It helps to regulate the amount of fluid in the body and maintain the pH balance.
