When LDL (low density lipoprotein) is taken up by cells during pinocytosis, which of the following steps in the processing of LDL and its receptor protein does not occur? LDL attaches to LDL receptors, which form clathrin-coated vesicles the vesicles fuse with endosomes, and LDL receptors are recycled LDL is digested in lysosomes, releasing cholesterol to the cytoplasm the endosomes fuse with lysosomes for digestion of the LDL LDL receptors are digested in the lysosomes along with the LDL

Secretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. In this process, the membrane of the secretory vesicle becomes part of the cell membrane because small pieces of the membrane are continually added to the cell membrane, one would expect the cell membrane to become larger and larger as secretion continues. The cell membrane stays the same size, however. Explain how this happens.
Secretory vesicles (destined for exocytosis) that fuse with the plasma membrane only in an intermittent manner (often requiring an environmental signal) are properly referred to as: constitutive secretory vesicles (like those that carry lipids, such as phosphatidylcholine) the v-SNARES the endosomes the t-SNARES regulated secretory vesicles (like those that carry hormones, such as insulin)
Secretory vesicles (destined for exocytosis) that fuse with the plasma membrane continuously, with no requirement for hormones or any other environmental signal, are properly referred to as: the v-SNARES constitutive secretory vesicles (like those that carry lipids, such as phosphatidylcholine) the endosomes regulated secretory vesicles (like those that carry hormones, such as insulin) the t-SNARES
The lateral movement of transmembrane proteins can be restricted by several diffrent mechanisms. In gut epithelial cells,which mechanisms best describes how proteins involved in nutrient intake are restricted to the apical surface and protiens involved in nutrient release are restricted to the basal and lateral surfaces? proteins are tethered to proteins on the surface of another cell proteins movement is limited by a diffusion barrier proteins are tethered to specific phospholipids proteins are tethered to the cell cortex proteins are tethered to the extracellular matrix
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)
Proteins 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.
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?
