Explanation:
Detailed explanation-1: -Steroid hormones are made up of fats and oils, which means they are not soluble in water. They are considered to be hydrophobic. They are lipid-derived hormones which means they can pass through the lipids. The cell membrane comprises a phospholipid bilayer that allows the passage of the hormones through them.
Detailed explanation-2: -A transport protein completely spans the membrane, and allows certain molecules or ions to diffuse across the membrane. Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion.
