What is the daily potassium requirement of humans for optimal cell functioning?

A. 20 mEq
B. 60 mEq
C. 3.5 mEq
D. 8.5 mEq

Answer :

The daily potassium requirement for optimal cell functioning in humans is primarily aimed at maintaining proper physiological functions such as muscle contraction, nerve signals, and fluid balance. Potassium is an essential mineral and electrolyte that is vital for several bodily functions.

Among the options provided:

(A) 20 mEq

(B) 60 mEq

(C) 3.5 mEq

(D) 8.5 mEq

The correct answer is (B) 60 mEq.

Explanation:

  1. Importance of Potassium:

    • Potassium plays a critical role in maintaining normal cellular functions, including the transmission of nerve impulses, the contraction of muscles, and the balance of fluids within the body.

  2. Daily Requirement:

    • The recommended daily intake of potassium for adults is approximately 60 to 100 mEq per day. The value may vary slightly depending on dietary guidelines and individual health needs.

  3. Dietary Sources:

    • Potassium can be found in a variety of foods such as bananas, oranges, potatoes, spinach, and beans, providing a natural source to meet daily requirements.

  4. Health Implications:

    • Insufficient potassium intake can lead to hypokalemia, which can cause muscle weakness, cramps, and disruptions in heart function.
    • Excessive potassium, on the other hand, may lead to hyperkalemia, which can be dangerous and lead to cardiac issues.

It's important to maintain a balanced diet to ensure adequate potassium intake for overall health.
