The process of transporting materials in a cell involves a positive change in the amount of free energy in the cell. Which of the following best describes how this process affects the cell? The process is non-spontaneous and causes an increase in entropy.
The process is non-spontaneous and moves the cell away from equilibrium.
The process is spontaneous and can be used to do work in the cell.
The process is spontaneous and releases heat to the cell's surroundings.

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.)
