It is a catabolic pathway common to fermentation and respiration. These were the bacteria. This process is carried on by eukaryotes as well. In glycolysis, the six-carbon glucose molecule is split into two molecules of a three carbon compound, pyruvic acid. Each body cell respires as well as the lungs.
Respiration involves oxidation of pyruvic acid to carbon dioxide and water.
1. takes place in Krebb and ETC 2. B. structure of mitochondria 1. ATP and pyruvic acid can enter that membrane. AcetylcoA is the link between glycolysis and the Krebb cycle. D. Krebb cycle 1.
