    I've watched like 5 videos about ATP and have read a lot of articles about it. Thankfully i found this.

    Here is the core biology course for ATP overview:
    6 O2 + C 6 H 12 O 6 -> 6 CO2 + 6 H2O + ATP
    oxygen + glucose -> carbon dioxide + water + energy
    Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen. Glycolysis takes place in the cytoplasm. The Kreb cycle and electron transport take place inside the mitochondria. Glycolysis is the process in which one molecule of glucose is broken in half, producing two molecules of pyruvic acid of a 3 carbon compounds. During the Kreb cycle, pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions. The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.

    Hello Khan Academy friends, DP biology teacher here (similar to AP). One thing I want to make clear that is video does not is about the points in time where energy is released and absorbed (needed). There are a few processes where bonds are formed and broken in the model shown. In chemistry, when bonds are formed energy is released. Energy is needed, or absorbed, when a bond needs to be broken. Yes this includes the phosphate group bond in ATP!!! Even though the phosphate group bonds are unstable, it is still a form of stability which needs energy to break it (some people replace unstable with high energy, this is why I tend to disagree with that terminology). It just happens to be that the formation of the bond with the phosphate group and the oxygen in the water molecule is more stable and thus releases the energy. The placement of energy before and after in the system comes out to mean energy is released in this chemical reaction, but that is from the formation of the bond with water rather then the breaking of ATP.

    It does take energy to recreate ATP from ADP and P, but it is important to note that making a bond involves a release of energy. The actual creation of the bond between P and ADP would release a bit of energy, but overall the creation of the unstable ATP from the more stable ADP would require energy. Similar to the hydrolysis of ATP, which overall releases energy because such stable products are formed from unstable ATP, but involves an initial absorption of energy to actually break the bond of the third phosphate. It's tricky and I've always been confused about the way it was taught, until recently.

    The energy stored in ATP isn't due to the negative charges of pohosphate groups? they normally tend to repulse each other but as they are kept together by the energy of the bond when they split they release that energy. Here is my curiosity: ATP can just split only one phosphate group but not the second one... Is possible that even the second phosphate group could be split? In that case it would release energy anyways (I presume), probably a lower amount of it but it could happen because of the repulsion between the second and the first phospate grupo (the one attached to the ribose).

    How can we benefit from the energy we get by ATP Hydrolysis? By phosphorylation or by using the released energy (i think it is called gibbs energy) or both ways?

    so basically when carbs protiens and fats are digested the energy taken from them is made into ATP so when the body needs energy the ATP turns into ADP with energy ? but what happens to ADP afterwards ??

  • @FrozenVodka1
    @FrozenVodka1 3 года назад

    Okay, im not comprehending something. ATP is the currency for energy. When we use energy we are using ATP. But, ADP is considered energy released and ATP is considered energy stored?

    • @marissa9474
      @marissa9474 3 года назад +1

      yes ATP still has the three phosphors and thus the high energy stored within it, but when ATP -> ADP + P the energy is thus released, due to the broken bond
