Which of the following is true about steroid hormones?Multiple ChoiceSteroid hormones can diffuse through the lipid bilayer.Receptors for steroid hormones are found on the cell membrane.Steroid hormones use a second messenger mechanism to cause an effect in the cell.Steroid hormones can travel freely in the blood.

What is the relationship between steroid hormones and cell membranes?Multiple choice question.Steroid hormones can diffuse easily through the cell membrane.Steroid hormones are transported in the cell by hormone channel proteins because they are too large to easily diffuse through the membrane.Steroid hormones bind to the outside of cell membrane because they can't diffuse through the membrane.

Hormones can be classified based on the chemical composition. Answer the following questions comparing steroid hormones and nonsteroid hormones.Hormone enters the cell directly.multiple choice 1Steroid hormoneNonsteroid hormoneBoth Receptor is inside the cell.multiple choice 2Steroid hormoneNonsteroid hormoneBoth Stimulates transcription of DNA.multiple choice 3Steroid hormoneNonsteroid hormoneBoth Receptor is on the cell membrane.multiple choice 4Steroid hormoneNonsteroid hormoneBoth Results in metabolic changes in the cellmultiple choice 5Steroid hormoneNonsteroid hormoneBoth

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.

When a steroid hormone binds to its target cell receptor, it:Group of answer choicesalters the membrane’s permeability to G proteins.is converted into cholesterol, which acts as a second messenger.causes the formation of releasing hormones.turns specific genes of the nuclear DNA on or off.causes the formation of cyclic AMP

Select all that applyBecause they are weakly bound to plasma proteins, steroid hormones can circulate in the blood for long periods of time. Which of the following mechanisms contribute to this?Multiple select question.When bound to plasma proteins, steroid hormones are protected from enzymatic degradation.When bound to plasma proteins, steroid hormones are more easily transported inside of cells.After binding with plasma proteins, steroid hormones undergo slight modifications that stabilize them.When bound to plasma proteins, steroid hormones are less likely to be excreted by the kidneys
