Detailed explanation-1: -Cell-surface receptors come in three main types: ion channel receptors, GPCRs, and enzyme-linked receptors. When a ligand binds an ion channel receptor, a channel through the plasma membrane opens that allows specific ions to pass through.
Detailed explanation-2: -Membrane receptors are mainly divided by structure and function into 3 classes: The ion channel linked receptor; The enzyme-linked receptor; and The G protein-coupled receptor.
Detailed explanation-3: -The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
Detailed explanation-4: -If this is not present on the plasma membrane and is present on nucleus, then it makes it as intracellular receptor. So our answer to the question which receptor is not a membrane receptor, is option Number D. That is steroid hormone receptor.
