Biological role of sodium and potassium
Answers
Potassium is an essential mineral micronutrient and is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. Potassium is necessary for the function of all living cells, and is thus present in all plant and animal tissues.
The Role of Potassium and Sodium in Your Diet. Potassium and sodium are electrolytes needed for the body to function normally and help maintain fluid and blood volume in the body. However, a person can get high blood pressure by consuming too much sodium and not enough potassium.
Sodium ions are primarily found inside the human cells such as Nerve Cells. They regulate the flow of water across the membrane. ... Potassium ions acts as cofactor for certain enzymes such as pyruvate kinase. Potassium is important in heart function and in skeleton and muscle contraction.

biological role of sodium :-
# Sodium ions are primarily found inside the human cells such as Nerve Cells. They regulate the flow of water across the membrane.
# They are needed for transport of sugars and amino acids into the cells.
# Sodium maintains the electrolyte balance in the body.
biological role of potassium :-
# Potassium ions are primarily found inside the cell.
# Potassium ions maintain the osmolarity (the concentration of a solution expressed as the total number of solute particles per litre) of the cell. They also regulate the opening and the closing of the stomata.
# Potassium ions acts as cofactor for certain enzymes such as pyruvate kinase.
# Potassium is important in heart function and in skeleton and muscle contraction.
# Diets with low potassium leads to hypertension.
# It maintains the electrolyte balance in the body.
