D
Insulin
Verified step by step guidance1
Identify the hormones listed in the options and their primary functions: Cortisol, Epinephrine, Aldosterone, and Insulin.
Understand that the adrenal cortex is part of the adrenal glands, which are located on top of the kidneys and produce various hormones.
Recognize that cortisol is a glucocorticoid hormone produced in the adrenal cortex, which plays a role in increasing blood sugar levels by stimulating gluconeogenesis in the liver.
Differentiate between the hormones: Epinephrine is produced in the adrenal medulla and primarily prepares the body for 'fight or flight' responses; Aldosterone regulates sodium and potassium levels; Insulin, produced by the pancreas, decreases blood sugar levels.
Conclude that the hormone produced in the adrenal cortex that increases blood sugar levels is cortisol, based on its function and origin.
