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

Lesson on the Glycerol Phosphate (aka Glycerol-3-Phosphate) Shuttle. NADH produced from glycolysis is unable to enter into the mitochondria because the mitochondrial inner membrane is impermeable and highly selective. Therefore, the cell has to “smuggle” in the protons and electrons from the cytosolic NADH into the electron transport chain, and the cell does this by using the glycerol-phosphate shuttle system.

Hey everyone. In this lesson you will be introduced to the glycerol-phosphate shuttle system. We will discuss in detail why we require this shuttle system, how it operates and how much ATP is generated in the process.

  1. Omg. Thank you. Thank you. Thank you. I have had this surface-level understanding that NADH from glycolysis vs. from the TCA cycle are different in terms of ATP production, but I've never been able to understand it. Until now! Again, THANK YOU!
