When William H. was helping victims after a devastating earthquake in a region not prepared to swiftly set up adequate temporary shelter, he developed severe diarrhea. He was diagnosed as having cholera, a disease transmitted through unsanitary water supplies contaminated by fecal material from infected indiv iduals. The toxin produced by cholera bacteria causes Cl- channels in the lurninal membranes of the intestinal cells to stay open, thereby increasing the secretion of Cl- from the cells into the intestinal tract lumen. By what mechanisms would Na+ and water be secreted into the lumen in conjunction with Cl- secretion? How does this secretory response account for the severe diarrhea that is characteristic of cholera?
Put the following structures in order according to the pathway of a secreted protein: a. plasma membrane b. Golgi bodies c. endoplasmic reticulum d. post-Golgi vesicles
Chemiosmosis involves a. the movement of electrons across the cell membrane. b. the movement of hydrogen atoms across a mitochondrial membrane. c. the movement of hydrogen ions across a mitochondrial membrane. d. the movement of glucose through the cell membrane.
