Which of the following statements regarding the movement of molecules across cell membranes is true?

In facilitated diffusion, a molecule is moved across a membrane against its
concentration gradient.

Water molecules are commonly actively transported out of cells.

Three examples of passive transport are diffusion, facilitated diffusion, and osmosis.

Polar molecules generally diffuse more readily through the plasma membrane than do nonpolar molecules of the same size.

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.)
