Final answer:
The primary result of the Krebs cycle in cellular respiration is the production of NADH and FADH2.
Step-by-step explanation:
One of the primary results of the Krebs cycle in cellular respiration is the production of NADH and FADH2. The Krebs cycle, also known as the citric acid cycle, is the second stage of cellular respiration and occurs in the mitochondria. During the Krebs cycle, acetyl-CoA is generated from pyruvate and enters the cycle, producing energy carriers NADH and FADH2, which will later donate electrons to the electron transport chain to produce ATP.
