Which of the following statements is not true for fatty acid oxidation?
A, fatty acid oxidation is a catabolic process that degrades fatty acids to Acetyl CoA. This statement is true. We do have the breaking down of lipids to fatty acids, and that eventually gets broken down into Acetyl CoA. Fatty acids are activated in the cytosol, that is true, and oxidize inside the mitochondrial matrix, that is also true. Remember, we utilize ATP in order to activate our fatty acid within the cytosol and then, when we get to the mitochondrial matrix, we undergo what's called beta oxidation to form our Acetyl CoA.
High-energy molecules produced in fatty acid oxidation are FADH2 and NADH. That is true. Fatty acid oxidation directly produces many ADP molecules. So the keyword here is directly. No, it does not directly make many ATP molecules here. Right. So we never cited that as a feature when it comes to fatty acid oxidation. So this statement here would be incorrect. Later on, we'll see how exactly this works, but for now, we know that directly, it doesn't produce many ATP molecules.
