Answer
The pathways used to catabolize fatty acids to carbon dioxide involve several key steps in cellular metabolism.
Solution
a
Beta-oxidation: Fatty acids are broken down in the mitochondria through a process called beta-oxidation. This process involves the removal of two-carbon units from the fatty acid chain, forming acetyl-CoA
b
Citric Acid Cycle (Krebs Cycle): The acetyl-CoA produced from beta-oxidation enters the citric acid cycle. Here, it is further oxidized to produce carbon dioxide, NADH, and FADH2
c
Electron Transport Chain: The NADH and FADH2 generated in the citric acid cycle donate electrons to the electron transport chain, leading to the production of ATP and the release of water and carbon dioxide as byproducts
Key Concept
Beta-oxidation, Citric Acid Cycle, and Electron Transport Chain
Explanation
Fatty acids are catabolized to carbon dioxide through a series of metabolic pathways, starting with beta-oxidation to produce acetyl-CoA, followed by the citric acid cycle and the electron transport chain, which ultimately generate ATP and release carbon dioxide.
