A hormone molecule binds to a receptor on a cell membrane. It doesnt enter the cell; rather, the binding activates a second messenger inside the cell that triggers an amplified response to the hormonal signal. Is the signaling molecule a steroid or a nonsteroid hormone?
Which of the following statements about hormones is correct? O steroid hormones are water soluble O epinephrine, norepinephrine, and dopamine are all catecholamines O receptor molecules of water soluble hormones are usually cell membrane proteins O water soluble hormones act on target cells by altering gene expression O Amine hormones are all lipid soluble O receptor molecules of lipid soluble hormones are usually in the cytoplasm or nucleus, but can also be in the cell membrane O insulin, growth hormone, and ecdysone are all examples of peptide hormones
The hormone mechanism which results in the release of intracellular Ca++ is the: 2nd messenger – adenylate cyclase mechanism PIP 2nd messenger mechanism O humoral mechanism Steroid hormone mechanism
Which of the following statements are false regarding the endocrine (hormones) in comparison to the paracrine system? (there may be more than one answer) Hormones are less stable than paracrine signals Hormones have a lower affinity for their receptors than paracrine signals Hormones are produced in a greater quantity than are paracrine signals Hormones are produced by most cell types; paracrine signals are only produced as a response to an insult (wound or infection). Hormones are produced from cells at a greater distance to their response elements than paracrine signaling.
The hormone mechanism which results in the release of intracellular Ca++ is the: Question options: PIP 2nd messenger mechanism humoral mechanism 2nd messenger – adenylate cyclase mechanism Steroid hormone mechanism
Which of the choices listed below is the correct order of events for the action of lipid-soluble hormones? O Hormone diffuses across cell membrane, hormone binds to receptors, translation of new protein, transcription of mRNA, cell's activity is altered. O Hormone binds to DNA, hormone binds to receptors, cell activity is altered, transcription, and translation. O Hormone diffuses across cell membrane, binds to receptors, receptors bind to DNA, transcription of mRNA, translation of new protein, cell's activity is altered. O Hormone binds to receptor, translation of protein, gene expression is turned on, cell's activity is altered. Save for Later Attempts: 0 of 3 used FB Submit Answer
If a hormone interacts with a membrane-bound receptor, then the cell’s DNA will be stimulated to synthesize and secrete a protein. True or False?
Which of the following is the best example of negative feedback for a steroid hormone? plasma membrane receptor activating a G protein plasma membrane receptor that activates the MAP Kinase pathway nuclear hormone receptor activating transcription of enzymes that synthesize the hormone nuclear receptor inhibiting its own transcription
Which of the following best explains how hormone antagonists work? Multiple Choice By flooding the cancerous cells with hormones By blocking actions of hormones that the cancer cells need to function By competing with uracil or cytarabine and metabolizing the nutrients required for hormone production By inhibiting folic acid, which is essential for blood cell and hormone production
Explain how the chemical nature of the plasma membrane acts on the two chemical categories of hormones, and thus the type of response each hormone can induce in a target cell. Be sure to thoroughly describe the two types of cellular responses.
Suppose that the circulating concentration of hor-mone is 10–10 M and the Kd for binding to its receptor is 10–8M. What fraction of the receptors will have hormone bound?If a meaningful physiological response occurs when 50% ofthe receptors have bound a hormone molecule, how muchwill the concentration of hormone have to rise to elicit aresponse? The fraction of receptors (R) bound to hormone(H) to form a receptor–hormone complex (R–H) is [R–H]/([R] + [R–H]) = [R–H]/[R]TOT = [H]/([H] + Kd).
Which of the following statements regarding Antidiuretic Hormone signaling is false? - it involves the posterior pituitary - involves a first order feedback loop - it is initiated by barorecptors in the heart signaling to the hypothalamus - ADH will act in the kidneys to increase water retention, in part by changing aquaporin abundance
