Thyroxin controls metabolism. Which process does thyroxin primarily regulate?

• A. Growth
• B. Digestion
• C. Blood sugar
• D. Metabolism

Answer: (D)

Thyroxin sets the body's energy-burning pace. It increases the basal metabolic rate, meaning it drives how quickly tissues use energy, process nutrients, and generate heat. Because metabolism covers all the body’s chemical reactions that sustain energy and function, thyroxin primarily regulates metabolism. Growth is mainly driven by growth hormone and related factors; blood sugar is controlled mainly by insulin and glucagon; digestion is influenced by many systems but is not the main process regulated by thyroxin.
