Question

Membrane receptors are used by which types of hormones?

Answer 1

Answer:

Lipid insoluble hormones/Peptide hormones

Explanation:

Hormones produce their effect by binding to speific receptor. These receptors may be intracellular or membranal.

Membrane receptors;

The lipid insoluble hormones cannot cross the plasma membrane thus their receptors are found on plasma membrane. These are usually peptide hormones.

Examples; Insulin.

Intracellular receptors;

The lipid soluble hormones can cross the plasma membrane thus their receptors are found in cytoplasm. These are usually steroidal hormones.

Example; Testosterone.
