Respuesta :
The light junction membrane protein is expected to be the least mobile, based on its function. The correct answer is option (D).
The least mobile of all the proteins in the body, lipid-tethered proteins (also known as glycosylphosphatidylinositol-linked proteins, or GPI-linked proteins) are proteins that are anchored to lipids to restrict the movement of the cell. Enzymes, receptors, and channels are not in any way connected to other molecules.
Genetic data cannot be transmitted from membrane proteins to the cytoplasm. Only DNA and RNA contain genetic information, and for RNA to transmit genetic information, it must exit the nucleus and be translated into a protein in the cytoplasm. If a protein has the signal to do so when protein synthesis is complete, it may travel to the membrane; otherwise, it may serve another purpose. The membrane protein can convey information to the cytoplasm and receive information from other cells, but never in the form of genetic information.
The complete question is:
