In glycolysis, during oxidation electrons are removed by:
Options
- AATP
- Bglyceraldehyde-3-phosphate
- CNAD ⁺
- Dmolecular oxygen.
Correct answer
C. NAD ⁺
Step-by-step solution
When 3-phosphoglyceraldehyde is converted into 1,3 diphosphoglyceric acid, two electrons and two protons are released which are utilised to convert NAD ⁺ to NADH . NAD ⁺+2 H ⁺+2 e ⁻ NADH + H ⁺ Related Theory Glycolysis is a partial breakdown of a sixcarbon glucose molecule into two, threecarbon molecules of pyruvate, 2 NADH , 2 H ⁺ , and 2 net ATP as a result of substrate-level phosphorylation. Glycolysis occurs in the cytoplasm of the cell.
