Essential Biochemistry - Biological Oxidation (Section 2 - No. 2)

What is the primary function of the glycerol 3-phosphate shuttle?

To transport ATP from the mitochondria to the cytosol

To transport electrons from cytosolic NADH into the mitochondria using FADH2.

To transport FADH2 from the mitochondria to the cytosol.

To move protons from the intermembrane space to the matrix.

The glycerol 3-phosphate shuttle transports electrons, ultimately reducing FAD.
