12. Fill in the blanks with the best answer from the list below. Answers are used only once, but not all are used. G-protein-coupled receptors (GPCRS) all have a similar structure with seven transmembrane domains. When a GPCR binds an extracellular signal, an intracellular G protein, composed of BLANK subunits, becomes activated. BLANK of the G-protein subunits are tethered to the plasma membrane by short lipid tails. When unstimulated, the a subunit contains BLANK, which is exchanged for BLANK on stimulation. The intrinsic BLANK activity of the a subunit is important for inactivating the G protein. BLANK inhibits this activity of the a subunit, thereby keeping the subunit in an active state. adenylyl cyclase Ca2+ cholera toxin CAMP diacylglycerol five four GDP phosphodiesterase AMP seven three ATP ATPase GTP twelve GTPase two

Why are ion channels necessary to transport ions into or out of a cell? Ions are too large to diffuse through the membrane. Ions are charged particles and cannot diffuse through the hydrophobic interior of the membrane. Ions do not need ion channels to move through the membrane. Ions bind to carrier proteins in the bloodstream, which must be removed before transport into the cell.
Which of the following would not inhibit signal transduction? a. Phosphate groups are removed from proteins. b. Endocytosis acts on receptors and their bound signals. c. Receptors and signaling molecules separate. d. Receptors and bound signaling molecules enter lysosomes. e. Autophosphorylation targets the cytoplasmic portion of the receptor.
A scientist compares the plasma membrane composition of an animal from the Mediterranean coast with one from the Mojave Desert. Which hypothesis is most likely to be correct? The cells from the Mediterranean coast animal will have more fluid plasma membranes The cells from the Mojave Desert animal will have a higher cholesterol concentration in the plasma membranes The cells’ plasma membranes will be indistinguishable The cells from the Mediterranean coast animal will have a higher glycoprotein content, while the cells from the Mojave Desert animal will have a higher lipoprotein content.
What property prevents the ligands of cell-surface receptors from entering the cell? The molecules bind to the extracellular domain. The molecules are hydrophilic and cannot penetrate the hydrophobic inferior of the plasma membrane. The molecules are attached to transport proteins that deliver them through the bloodstream to target cells. The ligands are able to penetrate the membrane and directly influence gene expression upon receptor binding.
All of the following are true of integrins except (a) they are receptor proteins (b) they help organize the cytoskeleton (c) they are part of the ECM (d) they are important in cell signaling (e) they are located in the plasma membrane
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.
Why are steroids able to diffuse across the plasma membrane? Their transport protein moves them through the membrane They are amphipathic, allowing them to interact with the entire phospholipid Cells express channels that let hormones flow down their concentration gradient into the cells They are non-polar molecules.
