Question

Where does the citric acid cycle occur in eukaryotes?
a. in the cytosol of cells
b. in the intermembrane space of mitochondria
c. in the inner membrane of mitochondria
d. in the matrix of mitochondria

Accepted Answer

Hello everyone. Let's look at our next problem in eukaryotic cells. The complete oxidation of pyrite carbon dioxide takes place inside. And we recall that piru bait is the end product of like Alexis. And then in the Krebs cycle it will be broken down with the end product of carbon dioxide. So let's look through our answer choices. Choice A says cytoplasm. Well, here's where that introductory part of the question is important. It says in eukaryotic cells um this takes place in pro carry attic cells in the cytoplasm but not in eukaryotic cells. So choice say not our answer here. Choice B says the outer chamber of mitochondria. Well that's not quite right. It does take place in the mitochondria but not the outer chamber. And so let's move on. Choice C. Says the strom A. Of the chloroplast. Well the strom of the core classes where you have the light harvesting, where sunlight excites an electron of a chlorophyll molecule and that electrons gets passed down to electron transport chain but not what we're looking for here. So finally we have choice the matrix of mitochondria. This is the inner chamber of the mitochondria. And this is where that complete oxidation of pirate bait. And the Krebs cycle takes place. So again, complete oxidation prove it takes place inside. Choice D the matrix of mitochondria. See you in the next video
