Suppose a new protein modification that is essential for proper ribosomal function has been discovered. When the protein is dissolved in water, it remains curled up. However, in the presence of an abundance of glucose, the protein molecule unfolds and attaches to lipid molecules, such as those that comprise the membrane of the cell. Which of the following conditions would MOST likely activate the protein? A.
gestational diabetes

B.
a high-fat meal

C.
sickle cell anemia

D.
a high-sugar meal

Which plant has a visible leaf modification that will it conserve water in extremely dry environments?

The process by which natural forces move weathered rock and soil brim one place to another is called

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: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic 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.)
