What is the correct order of the stages during aerobic respiration?
Options
- AKreb's cycle - Electron transport chain - Glycolysis
- BElectron transport chain - Krebs' cycle - Glycolysis
- CGlycolysis - Krebs' cycle - Electron transport chain
- DGlycolysis - Electron transport chain - Krebs' cycle
Correct answer
C. Glycolysis - Krebs' cycle - Electron transport chain
Step-by-step solution
Cellular respiration is the process in which energy stored in a glucose molecule is released by oxidation. During glycolysis, glucose is broken down into two molecules of pyruvate, which due to link reaction, get converted into acetyl CoA. This acetyl CoA enters the Kreb's cycle and gets converted into CO 2 producing NADH 2 and FADH 2 . This NADH 2 and FADH 2 are oxidized through oxidative phosphorylation to regenerate NAD and FAD and produce ATP.
