In this discussion, we will explore stretching and shrinking a graph, both vertically and horizontally. When you finish studying this lesson, you should be able to do a problem like this: GRAPH: [beautiful math coming... please be patient] $\,y=2{\text{e}}^{5x}\,$.
According to how it is treated, cellulose can be used to make paper, film, explosives, and plastics, in addition to having many other industrial uses. The paper in this book contains cellulose, as do some of the clothes you are wearing. For humans, cellulose is also a major source of needed fiber in our diet.
Explain the process of how a starch can become cellulose. First, a person eats a starch (i.e., a potato). The body may use some of the sugars in the chain. If there is extra, the body attaches a fatty acid to the end of the chain. The chain becomes a lipid. If the body ever needs extra energy, it will break the fatty acid from the chain. The sugar chain left over is cellulose.
