Name the location in the cell where the following catabolic processes take place:

c. β oxidation

Accepted Answer

Hi, everybody. Welcome back. Let's look at our next problem. True or false. Correct the statement. If it is false, beta oxidation is a catic process that takes place in the cytoplasm. So we're talking about two statements essentially or two facts about beta oxidation. And if this statement is false, we need to correct it. So let's recall it. Beta oxidation is that process by which you break down fatty acids for energy. So when carbohydrate intake is low or there's fasting going on, then the body can use fatty acids as an energy source. So what is a cat bolic process? A catic proc process we recall is one where larger and more complex molecules are broken down into simpler, smaller ones providing energy through that process. Well, in fatty acid oxidation, that is exactly what we're doing. We're starting with fatty acids which of course have those long chains and we're breaking them down into smaller and simpler ones as it breaks down the large fatty acid chains into two carbon units of acetyl coa. So part one of this statement is true. So beta oxidation is indeed a catic process. But where does it take place and this is the part that makes our statement false because beta oxidation does not take place in the cytoplasm, but in the mitochondrial matrix. And this makes sense because acetyl coa can enter the reb cycle which takes place in the mitochondria and the other product here, as well as acetyl coa, we know that again, this process to generate energy and the process of beta oxidation generates those high energy molecules of N A DH and FA DH two. And of course, the way they generate energy is by going through that process of oxidative phosphorylation to yield multiple molecules of A TP. So with these energy yielding processes all taking place in the mitochondria, it makes sense that we would have beta oxidation taking place there as well. When we talk about reactions with fatty acid in the cytoplasm, the fatty a fatty acid activation process that has to happen as sort of the precursor step to fatty acid oxidation, which converts our fatty acids into fatty acyl coa molecules. And that takes place in the cytoplasm. But those molecules are then transported into the mitochondrial matrix by a carnitine shuffle where they become attached to a carnitine instead of the coa and then the breakdown into acetyl coa N A DH fa DH two all takes place in the mitochondrial matrix. So our statement was false and the correct statement would be beta oxidation is a catic process that takes place in the mitochondrial matrix. So that is our correct answer here. Circle that whole thing and correcting the location where this process takes place. See you in the next video.
