Science
The breakdown of glucose has taken the following pathway : The sites ‘a’ and ‘b’ respectively are : options 1. Mitochondria and Oxygen deficient muscle cells 2. Cytoplasm and Oxygen rich muscle cells 3. Cytoplasm and Yeast cells 4. Cytoplasm and Oxygen deficient muscle cells
Answer
Cytoplasm and Oxygen deficient muscle cells
Reason — Glycolysis (Glucose → Pyruvate + energy) takes place in the cytoplasm of the cell and when oxygen is scarce, pyruvate is converted to lactic acid in oxygen-deficient (anaerobic) muscle cells, releasing a small amount of energy.
Hence the sites for (a) and (b) are cytoplasm and oxygen-deficient muscle cells respectively.
