Thyroxine
A. Regulates basal metabolic rate
B. Supports erythropoiesis
C. Influences water and electrolyte balance
D. Regulates blood calcium levels
Which of the above are correct?
Thyroxine regulates the basal metabolic rate and controls the metabolism of carbohydrates, proteins and fats. It also supports the process of red blood cell formation and influences the water and electrolyte balance. The blood calcium levels are regulated by thyrocalcitonin (not thyroxine).
