A disease resulted in mitochondria being unable to function properly. How could this most directly affect an organism’s ability to maintain homeostasis?

• Active Transport cannot maintain a concentration gradient in nerve cells.

• Osmosis cannot occur

• Gases such as carbon dioxide and oxygen could not diffuse in and out of the cells.

• Cells would be unable to use membrane proteins to carry out facilitated diffusion.
