Calcium ions (a) can act as second messengers (b) split calmodulin (c) are kept at higher concentration in the cytosol than in the extracellular fluid (d) are produced in the ER by protein kinases and protein phosphatases (e) typically terminate signaling cascades
During signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzyme catalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMP
Second-messenger systems ultimately bring about the desired cell response by inducing a change in the shape and function of particular designated intracellular proteins. (True or false?)
Histamine binds to the H1 G-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. If a mutation in the associated G-protein’s alpha subunit prevented the hydrolysis of GTP how would the allergic response change? More severe allergic response compared to normal G-protein signaling. Less severe allergic response compared to normal G-protein signaling. No allergic response. No change compared to normal G-protein signaling.
What distinguishes a steroid receptor from a receptor tyrosine kinase receptor or a G-protein-coupled receptor?
Figure 37.5 Heat shock proteins (HSP) are so named because they help refold misfolded proteins. In response to increased temperature (a “heat shock"), heat shock proteins are activated by release from the NR/HSP complex. At the same time, transcription of HSP genes is activated. Why do you think the cell responds to a heat shock by increasing the activity of proteins that help refold misfolded proteins?
Outline the three general means by which binding of a water soluble extracellular chemical messenger to its matching surface membrane receptor brings about the desired intracellular response.
When a signaling molecule binds with a receptor, (a) G proteins are inactivated (b) a third messenger is activated (c) cell signaling is terminated (d) cAMP is produced by the receptor (e) the receptor becomes activated
The hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.
Which of the following is incorrect about pathways activated by G-proteincoupled receptors? a. The extracellular signaling molecule is the first messenger. b. When activated, plasma membrane-bound G protein canswitch on an effector. c. Second messengers enter the nucleus. d. ATP converts to cAMP to activate protein kinases. e. Protein kinases phosphorylate molecules to change cellularactivity.
Endocrine signals are transmitted more slowly than paracrine signals because.___ the ligands are transported through the bloodstream and travel greater distances the target and signaling cells are close together the ligands are degraded rapidly the ligands don't bind to carrier proteins during transport
Describe the contribution of each of the following to establishing and maintaining membrane potential: (a) the Na+K+ pump, (b) passive movement of K+ across the membrane, (c) passive movement of Na+ across the membrane, and (d) the large intracellular anions.
