There are two main types of receptors that mediate signal transduction in cells internal re ceptors and intracellular receptors How do these receptors differ A The ligand receptor complex directly enters the nucleus when cell surface receptors are used Internal receptors initiate a signaling cascade that indirectly influences the making of a functional protein B C D Internal receptors bind to ligands that are hydrophobic and can pass through the mem brane while cell surface receptors bind to hydrophilic ligands Internal receptors bind to ligands that are hydrophilic while cell surface receptors bind to hydrophobic ligands Cell surface receptors bind to ligands initiating a signaling cascade which in turn trig gers the ligand receptor complex to enter the nucleus initiating protein synthesis
