Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): During aerobic respiration, the inner mitochondrial membrane is impermeable to the NADH produced in the cytoplasm during glycolysis. 

Reason (R): Special shuttle systems, such as the Malate-Aspartate shuttle or Glycerol-3-Phosphate shuttle, are required to transport the reducing equivalents (electrons) from cytosolic NADH into the mitochondrial matrix.
