100-150 words (need now) Environmental interactions: A human pancreatic cell obtains Oz, fuel molecules such as glucose, and building
materials such as amino acids and cholesterol from its environment, and it releases
co, as a waste product of cellular respiration. In response to hormonal signals, the
cell secretes digestive enzymes. It also regulates its ion concentrations by
exchange with its environment. Based on what you have just learned about the
structure and function of cellular membranes, describe how such a cell
accomplishes these interactions with its environment.
