Now, only specific types of cells in our body are actually able to undergo gluconeogenesis. So these include liver cells and to a small extent, kidney cells, because it's the liver and the kidneys that are responsible for actually regulating and maintaining the proper glucose level in our blood. So liver cells, hepatitis and kidney cells are able to actually undergo the process of gluconeogenesis. And cells like cardiac muscle cells, skeleton muscle cells and brain cells cannot actually undergo gluconeogenesis. These cells depend on liver cells and kidney cells ability to actually create these glucose molecules, dump these glucose molecules into the blood plasma, and then the blood plasma brings these glucose molecules to the cells, like the cardiac cells, muscle cells and brain cells of our body. Now, let's briefly discuss where we actually obtained these non sugar precursor molecules.
