Why is it necessary for cells to maintain homeostatic control over their internal environments? A) Internal cell environments are very different from the external environment B) Internal temperatures must be kept as high as possible to enable metabolism C) The chemical reactions of life can only take place within specific ranges of temperature, pH, ion concentration, etc. D) All of the above E) A and C but not B

Step 1
Cells maintain a distinct internal environment that is different from the external environment. This difference is crucial because the internal environment of the cell is specifically tailored to support the various biochemical processes that occur within it. The Show more…

What is the primary reason internal homeostasis must be maintained? A. Unregulated variations cause the cells' DNA to mutate. B. Wide swings in the internal environment interfere with normal metabolic reactions. C• Enzymes must retain their correct three-dimensional structure.
