List the components of the animal plasma membrane and provide a function for each.
Membranes serve as a locus for biochemical reactions.
In the middle of the night, the membranes from a tissue sample are analyzed for their phospholipid content. In the middle of a warm day, another sample is taken and the membrane lipid content has changed. One function of cell membranes is compartmentalization. Based on your understanding of this concept, give two examples of how intermixing of intracellular contents would be harmful. List the criteria by which simple, facilitated, and active transport systems can distinguished in living systems.
