Question

Potassium is a necessary nutrient to maintain the function of our cells. What would occur to a person that is deficient in potassium?

a) Increased nerve and muscle activity.
b) Enhanced cellular communication.
c) Impaired nerve and muscle function.
d) Accelerated metabolic rate.

Answer 1

A potassium deficiency may lead to impaired nerve and muscle function due to the mineral's role in cellular activities such as muscle contractions and nerve impulse transmission. Maintaining proper levels of potassium is vital for overall health and to prevent conditions like muscle weakness or dangerous heart irregularities.

Step-by-step explanation:

Potassium is an essential nutrient that plays a key role in maintaining cellular function, particularly in nerve and muscle cells. A deficiency in potassium can lead to impaired nerve and muscle function due to its role in establishing the resting membrane potential and facilitating action potentials. When potassium levels are low, the body may experience issues like muscle weakness, cramps, arrhythmias, and general fatigue due to the imbalance of electrolytes.

Moreover, potassium is the major intracellular cation that helps maintain the sodium-potassium balance through active transport mechanisms, requiring ATP. This balance is critical for proper muscle contractions, nerve impulse transmission, and heart function. The required daily intake of potassium is approximately 4700 mg, which should be maintained to prevent the adverse effects of hypokalemia, such as paralysis or life-threatening cardiac arrhythmias.
