1. Cushing’s disease disease; hypercortisolism, (moon face) some symptoms mimics diabetes mellitus and may result from adrenal, pituitary tumor Cellular Organelles and their functions: Nucleus: genetic info Ribosomes: stations for protein synthesis Rough ER: modifies proteins, protein synthesis Smooth ER: [lipids, cortisol, steroids], detox storage for calcium. Golgi apparatus: packages and transports proteins Lysosomes: kills stuff, bacteria, virus, old cells. List the following Steps of protein synthesis  Intracellular and extracellular ions  Function of Na+/K+ pump 3 sodium in 2 Potassium out  Rules of diffusion  Hormonal classification Amines: simple molecules Proteins and peptides: made from amino acids Steroids: derived from cholesterol  Hormones of the anterior pituitary
