The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well
as proteins that are targeted for secretion from the cell.For example, consider these two proteins:1. Phosphofructokinase (PFK) is an enzyme that functions in the cytoplasm duringglycolysis.2. Insulin, a protein that regulates blood sugar levels, is secreted from specializedpancreatic cells.Assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.For each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (Note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)Options:Cytoplasm only, ER --> cytoplasm, ER --> Golgi --> outside cell, cytoplasm --> ER --> outside cell, Golgi --> ER --> outside cell, cytoplasm --> Golgi --> outside cell, nucleus --> cytoplasm, ER --> Golgi --> cytoplasmProtein Targeting PathwayPFK _______________Insulin _______________
Here we have a metal and two nonmetals (sulfur and iodine).
They are all solid at room temperature. Metals form cations and are good conductors of electricity. They are not from the same family, therefore, they do not have the same number of valence electrons.
<h3><em>Starch is a indicator in the iodometric titration and it turns deep dark blue when iodine is present in a solution. The starch under warming condition forms amylose and amylo pectins which combine with iodine to produce dark blue color.In absence of iodide ion starch indicator is colorless.</em></h3>
You can automatically eliminate B and D because they have little to do with the movement of the body. And it's not A because the skeletal system doesn't have the signals to tell the muscular system what to do.
