Question

which of the following are functions of potassium in the human body?
check all that apply
maintenance of proper fluid balance
transmission of nerve impulses
structural component of hair
activation of enzymes and hormones necessary for energy metabolism
maintenance of acid - base balance

Explanation:

• Maintenance of proper fluid balance: Potassium is an important electrolyte that helps in maintaining the fluid balance in the body by regulating the movement of fluids in and out of cells.
• Transmission of nerve impulses: It plays a crucial role in the generation and transmission of nerve impulses. Changes in potassium levels can affect the electrical activity of nerves.
• Activation of enzymes and hormones necessary for energy metabolism: Potassium is involved in various enzymatic reactions related to energy metabolism, such as in the breakdown of glucose.
• Maintenance of acid - base balance: Along with other electrolytes, potassium helps in maintaining the body's acid - base balance by participating in buffering systems.

• Structural component of hair: Keratin (a protein) is the main structural component of hair, not potassium.

Answer:

Maintenance of proper fluid balance, Transmission of nerve impulses, Activation of enzymes and hormones necessary for energy metabolism, Maintenance of acid - base balance.
