Select the best answer or answers from the choices given: A pancreas cell makes proteins (enzymes) that it releases to the small intestine. Which of the following best describes the path of these proteins from synthesis to exocytosis at the pancreatic cell’s plasma membrane (PM)? (a) Golgi S rough ER S PM, (b) smooth ER S Golgi S lysosome S PM, (c) rough ER S Golgi S PM, (d) nucleus S Golgi S PM.
Tight junctions are protein junctions that provide a water-tight seal between cells. They ensure that materials must enter the cells (through diffusion or active transport) to pass through the tissue. Tight junctions are characteristic of cells lining the digestive tract, where materials are required to pass through cells (not between them) before they can travel into the blood.
Can someone explain more clearly why lining the digestive tract?
Explain why the statement is correct.
Which is true of the ribosomes of endoderm cells of the Cnidaria (jellyfish)?
They: are attached to the Rough Endoplasmic reticulum (RER) and carry out the synthesis of the primary structure of proteins

- 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_forwardWhen 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_forward

In response to hormonal signals, the cellsecretes digestive enzymes. It also regulates its ion concentrationsby exchange with its environment.

However, all activit ort, involve energy. This leads us to another characte As stated in the first section of this lesson, maintaining homeostasis requires ise this in poweringarrow_forwardFibroblasts are motile cells that “creep” about in the connective tissue of the body where they play a number of roles, including secretion of the extracellular matrix and initiating certain wound healing events. These cells do not usually have microvilli nor do they express the actin-binding protein villin; both of these properties are characteristic of certain epithelial cells, such as those lining the intestine and kidneys. Remarkably enough, however, if one artificially engineers fibroblast cells to produce the villin protein, microvilli form on the fibroblasts. Given what you know about the function of villin, why might this striking change in cell morphology occur?arrow_forwardThere are 4 basic tissues in the human body. For each of the following organs/structures describe the location and function of at least three basic tissues found in them.

You have been able to develop the vaccine but now the challenge is how the vaccine will enter the cells of the body when you inject it.

- Cells that line your intestines are specialized for nutrient absorbtion and are known to possess numerous membrane proteins that transport small molecules and ions across the plasma membrane. Which of the following cell structures would you expect to be required for this function of the cells? The endoplasmic reticulum Lysosomes Peroxisomes or Cell wallsarrow_forwardProteins that are trafficked through the secretory pathway of eukaryotic cells are never exposed directly to the cytoplasm. Which of the following is the best explanation for why this is true? A. Cells that specialize in protein secretion lack cytoplasm, because protein synthesis machinery takes up the volume of the cell instead. B. For a protein that will be secreted, during the whole time that it spends inside of the cell, it is enclosed within other membrane-bound compartments. C. While a protein is in the secretory pathway, it is surrounded by a dense cloud of ions that protect it from the cytoplasm. D. A protein that will be secreted is not synthesized by ribosomes in the cytoplasm; instead, it is synthesized by proteins at the plasma membrane and fed directly into the extracellular space.arrow_forwardThe nutrient-absorbing intestinal cells have a multitude of finger like projections in contact with the digested food (see Figure 16-20, p. 602). Based on your knowledge of structure— function relationships, explain the functional advantage of this structural feature. (Answers are in Appendix C.)arrow_forward
