Glucocorticoids are characterized by all except:
1. Glucocorticoids stimulate the breakdown of muscle proteins into amino acids.
2. Cortisol is a glucocorticoid.
3. Glucocorticoids stimulate the pancreas to produce the enzymes needed for gluconeogenesis.
4. Glucocorticoids are released during times of stress.
