Final answer:
Glucocorticoids are the class of adrenal gland hormones that provide resistance to stress, produce anti-inflammatory effects, and promote normal metabolism for ATP production.
Step-by-step explanation:
The class of adrenal gland hormones that provides resistance to stress, produces anti-inflammatory effects, and promotes normal metabolism to ensure adequate quantities of ATP is glucocorticoids. Glucocorticoids, such as cortisol, primarily affect glucose metabolism by stimulating glucose synthesis. They also have anti-inflammatory properties through inhibition of the immune system.
