Verified step by step guidance1
Understand the concept of intracellular receptors: Intracellular receptors are located inside the cell, typically in the cytoplasm or nucleus, and are activated by hormones that can pass through the cell membrane.
Identify the types of hormones that typically have intracellular receptors: These are usually steroid hormones or thyroid hormones, which are lipid-soluble and can easily cross the cell membrane.
Examine the list of hormones provided: Glucagon, Insulin, Cortisol, and Adrenaline.
Determine which of these hormones are steroid hormones: Cortisol is a steroid hormone, while Glucagon, Insulin, and Adrenaline are not.
Conclude that Cortisol, being a steroid hormone, has intracellular receptors, as it can pass through the cell membrane and bind to receptors inside the cell.
