Chapter 6.5, Problem 1TYK
Summary Introduction
Introduction:
The glucose molecule is converted into the pyruvate during the process of glycolysis. This breakdown of glucose into pyruvate occurs in the cytosol of eukaryotes. The pyruvate is then transported to the mitochondrial matrix where they are oxidized.
