Glycophorins are a type of membrane protein found on red blood cells. They allow red blood cells to circulate through the blood vessels without sticking to the walls of the blood vessels or to other cells. Describe how a glycophorin protein would be synthesized by the cell. Include
What parts of the cell are involved and what happens at each location.
The process of protein synthesis (i.e. transcription, translation, etc).
A human pancreatic cell obtains O2—and necessary molecules such as glucose, amino acids, and cholesterol—from its environment, and it releases CO2 as a waste product. In response to hormonal signals, the cell secretes digestive enzymes. It also regulates its ion concentrations by exchange with its environment.
Based on the structure and function of cellular membranes, describe how such a cell accomplishes these interactions with its environment.

- Exocytosis Exocytosis (below) is an active transport process in which a secretory vesicle fuses with the plasma membrane and expels its contents into the extracellular space. In multicellular organisms, various types of cells (e.g. endocrine cells and nerve cells) are specialized to manufacture products, such as proteins, and then export them from the cell to elsewhere in the body or outside it. (DID YOU KNOW? The contents of the Exocytosis (and its counterpart endocytosis) require energy because they involve maverment of cytoskeletal proteins. vesicle are expelled into the extracellular space. Plasma membrane Vesicle fuses with the plasma membrane. Vesicle from the Golgi carrying molecules for export moves to the perimeter of the cell. From Golgi apparatus Nerve cell NT Golgi apparatus forming vesicles Nerve cell The transport of Golgi vesicles to the edge of the cell and their expulsion from the cell occurs through the activity of the cyloskeleton. This requires energy (ATP).…arrow_forwardWhen 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_forwardThe tails of the phospholipids of the plasma membrane are composed of _____ and are _____? a. phosphate groups; hydrophobic b. fatty acid groups; hydrophilic c. phosphate groups; hydrophilic d. fatty acid groups; hydrophobicarrow_forward
