Question

Cells in a cat's pancreas produce insulin, but the cells in its heart do not. Which statement best explains this?

Answer 1

Answer:

The correct answer is: A. The genes for insulin production are not activated in heart cells.

Explanation:

DNA is present in practically every cell in an organism, but not every cell performs the same tasks as the rest. This happens because genes in the DNA   code for different types of proteins, from enzymes to transporters, that impact greatly on the function of a cell; and these genes can be activated or inactivated which will directly correlate to the type of cell and the function that it has.

If the cells in the pancreas can produce insulin but the cells in the heart can't it's because the cells in the heart have the genes for insulin production inactivated.

The amount of mitochondria and ribosomes does not directly affect the production of insulin.
