Microvilli increase the surface area of intestinalcells, providing more efficient absorption of nutrients.Microvilli are shown in profile and cross section in FigureQ11–1. From the dimensions given in the figure, estimatethe increase in surface area that microvilli provide (forthe portion of the plasma membrane in contact with thelumen of the gut) relative to the corresponding surface of acell with a “flat” plasma membrane.

- 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?arrow_forwardPlease answer both, thank youarrow_forwardPlease help me with this question.

- When the proteins of human gut epithelial cells adhere to each other so tightly that digestive enzymes from the intestinal lumen cannot pass between the cells, these proteins are exhibiting: unrestricted movement, similar to membrane phospholipids (like phosphatidylcholine) restricted movement, based on confinement by diffusion barriers (like tight junctions) restricted movement, based on tethering to extracellular molecules (like collagen) restricted movement, based on attachment to other cells (by proteins like keratin) restricted movement, based on anchoring to intracellular proteins (like spectrin)arrow_forwardview View Help O Editing AaBbCc AaBbCc No Spacing AaBbCc AaBbe Normal Heading 1 Heading Paragraph Styles 34) The RNA that has an anticodon and attaches to a specific amino acid is RNA. 35) T/F Buffers cause abrupt and large changes the pH of the body by releasing or binding H+ ions. 36) What is a dynamic equilibrium of your internal environment termed? 37) are membrane junctions that distribute tension across a sheet of cells. 38) T/F About 60% to 80% of the volume of most living cells consists of organic compounds. ictions: Onarrow_forwardPlease help me with this question.
