NADH + H+
A
Oxidation
B
Reduction
Explanation: 

Detailed explanation-1: -In this shuttle, NADH is oxidized to NAD+ in the cytosol and NAD+ is reduced to NADH in mitochondria. NAD+ is used as an electron acceptor during glycolysis, whereas NADH is used by mitochondrial complex I to drive the mitochondrial electron transport chain (ETC).

Detailed explanation-2: -The conversion of NAD+ to NADH, and vice versa, are essential reactions in creating ATP during what’s called cellular respiration. The food you consume goes through three phases to become energy: glycolysis, the Krebs Cycle, and the electron transport chain.

Detailed explanation-3: -RH2 + NAD+
