Question

Biological importance of sodium and potassium​

Answer 1

Answer:

Sodium is a micronutrient that aids in metabolism, and synthesis of chlorophyll in plants. It substitutes for potassium in several roles like aiding in the opening and closing of stomata and maintaining turgor pressure.

Answer 2

Explanation:

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.

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.
