What is the biological importance of elements of group 1?
Answers
Answer : -
biological importance of elements of group 1 : -
(1) Sodium ions are present in all extracellular fluids which transport nutrients to the cells.
(2) The concentration of sodium ion in extracellular fluids regulates the flow of water across the cell membrane.
(3) Sodium ions participate in the transmission of nerve signals.
(4) Potassium ions are within the cells. They are required for synthesis of proteins and in oxidation of glucose.
Explanation:
Sodium is used for the generation of nerves impulses and for maintenance of electrolyte balance and fluid balance.
Sodium ions are necessary for heart activities and certain metabolic functions. Health is affected when the body has too much and too little sodium.
They are needed for the transport of sugars and amino acids into the cells
Biological Importance 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 liter) of the cell. They also regulate the opening and the closing of the stomata.
Potassium ions act as cofactors for certain enzymes such as pyruvate kinase.
Potassium is important in heart function and in skeleton and muscle contraction.
Diets with low potassium lead to hypertension.
It maintains the electrolyte balance in the body.
