Answer #1

Because.

  • Cell membrane has many protein like integral, extrinsic having function of cell signalling, cell to cell recognition, transport etc.
  • So there is need to confine proteins to specific domain dor there catalytic activity and functioning.
  • Some domains like cytoplasmic and extracellular domain are responsible for the signal amplification and signal receiving respectively.
  • specific domain of each protein may be buried inside lipid bilayer to make proteins diffusible by there hydrophobic amino acid domains and some polar domains are present in protein on membrane proteins.

n humans, red blood cells have a number of proteins embedded in the cell membrane. One type of protein, the Rhfactor, is controlled by a single gene and is either present or missing from the red blood cells. If present, the individual has the Rh+phenotype. If missing, the individual has the Rh-phenotype. Rh+is the dominant to Rh-. Suppose that, in the Welsh population, the frequency of the Rh-phenotype is 0.04. Using the Hardy-Weinberg equations, calculate the frequency of the Rh+allele.

The movements of newly synthesized proteins can be followed through cells using a "pulse-chase" experiment.  During synthesis, proteins are tagged with a radioactive isotope (the "pulse"), then the cells are allowed to process the proteins for varying periods of time.  The locations of the radioactive proteins are then determined by isolating cell organelles and quantifying their levels of radioactivity. What would be the expected pathway for a protein that is secreted from the cell?

Obviously, acid-detecting proteins (that bind to protons) within the body are important to maintain homeostasis for a variety of physiological factors. There's a new plant-based toxin named Iocane that binds to and blocks all activity of these acid-detecting proteins. If you were poisoned with Iocane, what kinds of physiological effects would expect to see? Explain why you’d see those effects
