Verified step by step guidance1
Understand that NADH is a crucial electron carrier in cellular respiration, which is used to produce ATP.
Recall the main stages of cellular respiration: Glycolysis, Krebs Cycle (Citric Acid Cycle), and Electron Transport Chain.
Identify that Glycolysis occurs in the cytoplasm and produces a small amount of NADH.
Recognize that the Krebs Cycle, which takes place in the mitochondria, generates a significant amount of NADH by oxidizing acetyl-CoA.
Note that the Electron Transport Chain uses NADH to produce ATP but does not produce NADH itself. Therefore, the Krebs Cycle is the process that produces most of the NADH.
