Question

What happens to NADH in the GP shuttle?

Answer 1

In the glycerol phosphate shuttle, NADH produced in glycolysis is converted into NAD+ in the cytosol. The electrons from NADH are transferred to a molecule called DHAP, which is then converted into G3P. G3P can enter the mitochondria, where it is converted back into DHAP, generating NADH in the process.

Step-by-step explanation:

In the glycerol phosphate shuttle, NADH produced in glycolysis is converted into NAD+ in the cytosol. The electrons from NADH are transferred to a molecule called dihydroxyacetone phosphate (DHAP), which is then converted into glycerol-3-phosphate (G3P).

G3P can enter the mitochondria, where it is converted back into DHAP, generating NADH in the process. The electrons from the NADH generated in the mitochondria can then enter the electron transport chain to produce ATP.
