Thyroxin (or thyroid hormone) travels through the bloodstream acting on many target cells to increase:
Correct answer: C. Metabolism
- A. Blood sugar
- B. Blood calcium
- C. Metabolism
- D. Anti-inflammatory reactions
Explanation
Thyroxine, or thyroid hormone, travels through the bloodstream to increase metabolism by binding to receptors on target cells in various tissues. Once bound, it stimulates the production of proteins that regulate metabolic processes, including energy production and consumption. By activating these cellular processes across the body, thyroxine helps to elevate basal metabolic rate, promoting efficient energy utilization and overall metabolic activity.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
