Glycerol-Phosphate Shuttle | NADH, Electron Transport Chain and ATP Yield

The video explains the glycerol phosphate shuttle, a mechanism that allows NADH from glycolysis to contribute to ATP production despite the mitochondrial inner membrane's impermeability to NADH. The shuttle transfers protons and electrons from NADH to dihydroxyacetone phosphate, forming glycerol 3 phosphate, which is then converted back, transferring electrons to FAD, forming FADH2. This process ultimately leads to ATP production via the electron transport chain. The video also compares this process to NADH from the TCA cycle, highlighting differences in ATP yield due to the entry point in the electron transport chain.

Explain the significance of the mitochondrial inner membrane's composition in relation to NADH.

What happens to FADH2 after it is produced in the glycerol phosphate shuttle?

What is the difference in ATP yield between NADH produced from glycolysis and NADH produced from the TCA cycle?
