What do steroid and peptide hormones typically have incommon?(A) their solubility in cell membranes(B) their requirement for travel through the bloodstream(C) the location of their receptors(D) their reliance on signal transduction in the cell

Which of them have intracellular receptor ? (a) Peptide hormones(b) Steroid hormones(c) Iodothyroninesa & ba & ca, b & cb & c

Peptide hormonesMultiple Choiceare able to pass through the membrane and bind to a receptor in the cytoplasm.bind to a receptor in the plasma membrane.act much more slowly than steroid hormones.initiate gene expression.are composed of a complex of four carbon rings.

Which of the following statements best describes an important characteristic of the general steroid hormone receptor mechanism of action?Group of answer choicesSteroid receptors are bound to response elements even before binding to their ligand.Coactivator complexes that are recruited to ligand bound receptor remove acetyl groups from histones.Steroid hormone receptors are bound to heat shock proteins (hsps) in the inactive state before binding to a hormone.Helix 12 of the ligand binding domain is always positioned the same way regardless of binding to an agonist or an antagonist.Steroid receptors are always found in the nuclear cell membrane, which is why they are called nuclear receptors.

Non-steroid hormones cannot diffuse through the plasma membrane and so they are detected by receptor proteins on the cell’s surface which trigger the production of other molecules within the cell. Which general term describes these molecules that then continue the hormone’s signal within the cell?

What do all hormones have in common?Multiple ChoiceThey are steroids.They are organic compounds.They are inorganic compounds.They are proteins.
