Most peptide and protein hormones diffuse through the phospholipid bilayer of the target cell membrane to gain access to their receptor.

Question

Quizplus · Accepted Answer

Peptide and protein hormones cannot diffuse through the phospholipid bilayer due to their large size and hydrophilic nature. Instead, they bind to specific receptors on the outer surface of the cell membrane, triggering a signaling cascade within the cell.
