Tracing Glucose Through Cellular Respiration
Captions available
The idea
This capstone traces one glucose molecule's full breakdown, from glycolysis through the citric acid cycle and the electron transport chain, tallying its ATP, NADH, and FADH2 at each stage.
Where people slip
Counting only the four ATP made directly by substrate-level phosphorylation badly undercounts glucose's real yield — most of the energy is banked in NADH and FADH2 until the electron transport chain cashes it in.
