<u><em>-Describe the process of glycolysis. What part of the cell does this reaction take place in?
</em></u>
Glycolysis occurs in cytoplasm of the cell & does not require oxygen. Glycolysis occurs outside of the mitochondrion, in the cytosol. During Glycolysis a glucose molecules is split into two, 3-carbon pyruvate molecules.
<u><em>-Describe the Krebs cycle. What part of the cell does this reaction take place in?
</em></u>
In the presence of oxygen, pyruvic acid produces in glycolysis passes on the second stage of cellular respiration, the Krebs cycle. During the Krebs cycle, pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. The Krebs cycle occurs in the mitochondrial matrix.
