Verified step by step guidance

Understand that hormones can be classified based on their solubility and the location of their receptors. Hormones that are not lipid-soluble cannot pass through the cell membrane and thus bind to receptors on the cell surface.

Recognize that peptide hormones are composed of amino acids and are generally water-soluble, meaning they cannot easily cross the lipid bilayer of the cell membrane.

Identify that because peptide hormones are water-soluble, they bind to receptors located on the cell membrane, initiating a signal transduction pathway inside the cell.

Contrast this with steroid hormones, which are lipid-soluble and can pass through the cell membrane to bind to intracellular receptors.

Conclude that peptide hormones are the type of hormones that bind to receptors located on the cell membrane, as they are unable to cross the lipid bilayer due to their water-solubility.
