Question 1

Explain how a cell isolated from the pancreas would be the same as a muscle cell. How would the two cell types be different?

Accepted Answer

Both cell types would contain the same organelles; however, due to the very different functions of the two cells, the proportion of certain organelles would be different. For example, the pancreatic cell, which is involved in the production of digestive enzymes, would have an extensive rough ER network, while a muscle cell would have a large proportion of mitochondria to make the large amount of energy necessary for muscle contraction.
