During which stage in the complete oxidation of glucose are the greatest number of ATP molecules formed from ADP?
Options
- AConversion of pyruvic acid to acetyl Co-A
- BElectron transport chain
- CGlycolysis
- DKrebs cycle
Correct answer
B. Electron transport chain
Step-by-step solution
In glycolysis 4 ATP and 2 NADH ₂ molecules are formed. These 2 NADH ₂ molecules go to electron transport chain. In oxidative decarboxylation no ATP molecule is formed but two molecules of NADH ₂ are formed from two molecules of pyruvate. These two NADH ₂ go to electron transport chain. In Krebs cycle 2 ATP, 6 NADH ₂ and 2 FADH ₂ molecules are formed from two molecule of acetyl Co-A. These NADH ₂ and FADH ₂ go to electron transport chain. In electron transport chain all NADH ₂ and FADH ₂ pass to electron carriers an
