Final answer:
The Krebs cycle primarily results in the production of NADH and FADH2, which are crucial for ATP production in the electron transport chain.
Step-by-step explanation:
One of the main 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 or TCA cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate into carbon dioxide. In addition to NADH and FADH2, a small amount of ATP is also produced directly in the cycle. These molecules, particularly NADH and FADH2, carry high-energy electrons to the electron transport chain, where a large amount of ATP is generated through oxidative phosphorylation.
