The cell membrane becomes less permeable. C. The cell becomes inactive. D. A second messenger appears in the cytoplasm.arrow_forwardA rise in the intracellular Ca2+ concentration causes muscle cells to contract. in addition to an ATP- driven Ca2+ pump, muscle cells that contract quickly and regularly, such as those of the heart, have an additional type of Ca2+ pump—an antiport that exchanges Ca2+ for extracellular Na+ across the plasma membrane. The majority of the Ca2+ ions that have entered the cell during contraction are rapidly pumped back out of the cell by this antiport, thus allowing the cell to relax. ouabain and digitalis are used for treating patients with heart disease because they make heart muscle cells contract more strongly. both drugs function by partially inhibiting the Na+ pump in the plasma membrane of these cells. can you propose an explanation for the effects of the drugs in the patients? What will happen if too much of either drug is taken?arrow_forward

- Which of the following Ca++ ion channels removes calcium ions from the cytoplasm of the cell? 1. voltage-gated Ca++ channels 2. Na+/Ca++ active transport pumps 3. Ca++ uniporter 4. Na+/Ca++ exchanger Group of answer choices (A) 1 and 2 (B) 1, 2, and 3 (C) 2 and 4 (D) 2, 3, and 4 (E) 3 and 4arrow_forwardThe 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.arrow_forwardFor a signal to be sent down an axon of a nerve cell, an action potential must be generated. This is done by.. Select one: a. G-protein coupled receptors bind ligand, a phosphorylation cascade occurs, this causes a change in charge of the membrane due to the addition of phosphates allowing Na+ channels to open. b. Ligand-gated K+ channels open, allowing K+ to rush out of the cell and depolarize that part of the membrane. This change in charge opens neighboring voltage-gated channels. c. Ligand-gated Na+ channels open, allowing Na+ to rush in. This then depolarizes that region of the membrane resulting in opening neighboring voltage-gated channels. d. Receptor tyrosine kinases have two Na+ molecules bind, this opens voltage-gated channels allowing the “signal” to pass down the axon.arrow_forward
