1. Reduced electron carriers:
* NADH: Nicotinamide adenine dinucleotide (NAD+) is reduced to NADH, carrying high-energy electrons to the electron transport chain for further ATP production.
* FADH2: Flavin adenine dinucleotide (FAD) is reduced to FADH2, also carrying high-energy electrons to the electron transport chain.
2. Carbon dioxide (CO2): The Krebs cycle is a key step in cellular respiration, where organic molecules are broken down to release energy. This process involves the oxidation of carbon atoms, releasing CO2 as a byproduct.
3. Precursors for biosynthesis:
* Intermediates: Some of the molecules produced during the Krebs cycle (e.g., oxaloacetate, α-ketoglutarate) serve as precursors for the synthesis of other important molecules, such as amino acids, glucose, and fatty acids.
In summary, the Krebs cycle generates ATP, NADH, FADH2, CO2, and precursors for biosynthesis.
