9. Which hormone is matched incorrectly with its functions?
T3 and T4-thermogenic, increase oxygen consumption, increase protein catabolism, increase activity of metabolic enzymes and Na+ -K+ pumps

Glucocorticoids (cortisol)-promotes gluconeogenesis, causes the breakdown of skeletal muscle proteins, and enhances lipolysis
Growth Hormone (GH)-increases hepatic glucose output, triggers protein synthesis, and increases fat breakdown.
Leptin-increases hunger and decreases metabolic rate
Ghrelin-increases hunger
