  • You know ‘em, you love ‘em. They’re the powerhouse of the cell: mitochondria. They produce the ATP molecules that we use to do everything from talk to our friends to run a marathon. In this episode of Crash Course Biology, we’re taking a deep dive into cellular respiration, the process that produces the ATP inside of our mitochondria.
    Chapters:
    Getting Energy 00:00
    Mitochondria & ATP 1:22
    Cellular Respiration 2:29
    Glycolysis 4:18
    The Citric Acid Cycle 6:40
    The Electron Transport Chain 8:17
    Review & Credits 11:05

    How classy to credit your student coming up with the currency exchange model. Sammy is a fantastic educator. Love this channel!

    I had a great biology teacher, she was only marginally more unsuccesful in teaching me this one. This is a serious step up from previous episodes.

    Ah yes, I remember having to stand up in front of my biochemistry professor, Dr Robert boyd, and explain in detail the citric acid cycle. He was the chemistry department chair, and he was a brilliant researcher. I learned a lot from him.

    That "currency exchange" seems like it starts with wood and cotton and manufactures the whole bill rather than just exchange one currency for another. I love the metaphors and allegories you came up with.

    My energy cell aka mitochondria didn’t form properly. Therefore it’s like running on low battery for me 24/7. Weeks really like your videos. As I’m homeschooling we find these so fascinating and very informative

    So, ATP is not very energy dense, if the energy of a single glucose molecule can make 30 ATP molecules. 🤔

    🔬 10 million ATP particles are made every second...
    🔹 if you take the reciprocal...that means ...
    🔬 1 molecule is made every 100 nano seconds...
    ⚡ that's lightning fast ⚡

    12:35 But 10M ATP molecules... ok, but
    1) how many ATP molecules does the cell need per second?
    2) Or does it vary depending on the type of cell?
    3) Do some cells produce (and use) more ATP than others?
    4) Does the number of ATP produced and used vary throughout the day?
    5) Does the number of ATP produced and used vary during different activities (eg: thinking vs doing sports vs dreaming)?
    This gave me more questions ...

    How do we use 100 pounds of ATP daily if we don't consume 100 pounds of food? And if we do, it would be used with total efficiency and we wouldn't need to use the bathroom

    WHAT? You're telling me my body is preventing me from exploding naturally? I am disappointed.
    Also, if you're a hundred pounds you are way smaller than I thought, that's half my weight.
