In which cellular compartment does glycolysis (Embden-Meyerhof-Parnas pathway) take place in plant and animal cells?
Answer and explanation
Correct answer: D. Cytosol
- Step 1: Glycolysis is the universal pathway of glucose breakdown present in all living organisms.
- Step 2: It consists of a sequence of ten enzyme-catalyzed reactions that convert one molecule of glucose into two molecules of pyruvate.
- Step 3: All ten glycolytic enzymes are soluble proteins located in the cytoplasm (cytosol).
Answer
Cytosol (cytoplasm)
Why not the others: 'Mitochondrial matrix' is the site of the link reaction (PDH) and Krebs cycle; 'Inner mitochondrial membrane' contains the complexes of the electron transport system and ATP synthase; 'Peroxisome' is the site of fatty acid beta-oxidation and photorespiratory glycolate oxidation.
