  A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.[2] wickerpedia

    Friendly neighborhood microbiologist here. You’re right except for one thing: most cells can use sugar directly through anaerobic respiration. Mitochondria allow aerobic respiration, which utilizes oxygen and is far more efficient, albeit a bit slower, and produces carbon dioxide as its end product.

    Fun fact: ever wonder where your weight goes when you lose weight? CO2. You literally breathe most of it out.

    I can get as nerdy as you want if anyone has any questions.

      Maybe the way you do it. I lost 5 pounds this morning, you wouldn’t want to breathe.

        On that (brown) note: most of the solid part of shit is actually (dead) gut bacteria, not food waste

      BRB. Hyperventillating to test a theory…

      (Going to assume this just results in a smaller quantity of calories processed per breath before anyone get’s all sciencey on me.)

        It’s too hard to try to manually control a fast breath rate like that. What you want to do is to naturally push that up by doing a bunch of physical work so that you’re breathing heavily. Then you’ll be exhaling lots of carbon dioxide!

      What would happen if I got ATP injected directly in the blood stream? And what about the stomach? Skin?

        Depending on the concentration, it would hurt as it’s a bit of an acid, plus ATP outside of the cell is one of the mechanisms that drives inflammation, but it won’t give you extra energy or anything.

        ATP is used to transfer energy more than store it, more like a wire than a battery. The average adult has about 250g of ATP in their body (for my fellow Americans: about one rather chunky hamster) but it’s recycled about 200 times a day, so would require 50kg (6 watermelons or two average labradoodles) if it was used and discarded.

        ATP has been around since the beginning of life or near enough, and evolution is a deranged, cat-piss-soaked hoarder that makes use of whatever is already lying around, so ATP also does several things beyond energy transfer. This also means where ATP is allowed and in what quantity is fairly controlled. To that end, there’s a class of enzyme called ectonucleotidases that’s found on the outside of cells. One of the things it does is keep the level of circulating ATP and things like it low, so whatever was injected would get chopped up pretty quick.

    Well, they can, but its not very efficient. They produce 4 atp at the cost of 2 atp

  It just means it’s the system that turns food molecules and oxygen into energy for the cell. The cell itself doesn’t know how to do this which is quite spectacular when you think about it. So if the mitochondria died the cell would die.

    There are human cells without mitochondria, and plenty of energy chains outside of mitochondrial action.

    There are, in fact lots of them: your red blood cells, for example.

    Mitochondria are more efficient at energy production, not the only source. Red cells use glycolysis.

  When cells devide there’s a top cell and a bottom cell, the bottom cell is where the powerhouse is generated
