Mobile Respiration and the Mighty Mitochondria

Discover how ATP is made in three steps of cardio mobile respiration with the Amoeba Sisters! This additionally compares this course of to photosynthesis and introduces ATP construction. This video has a handout right here:

We respect suggestions on our movies and pin clarifications on our movies if wanted. We do want we had been extra clear stating that the Krebs cycle “‘not directly” requires oxygen” as an alternative of simply stating it “requires oxygen” —as we don’t need to indicate that oxygen is a reactant within the Krebs cycle (Citric Acid Cycle). Whereas oxygen just isn’t a reactant for the Krebs Cycle, the oxidation steps of the Krebs Cycle can not happen with out the presence of oxygen. (Thus, the Krebs Cycle is taken into account an cardio course of)

36 ATP? 38 ATP? The large factor we need to emphasize, as we do within the video, is that this quantity is an estimate. It is seemingly not at the same time as excessive as these numbers everytime. And concerning the video notice about how ATP could must be used to shuttle in NADH from glycolysis—here’s a query answered by Miller and Levine that you could be discover useful:

  1. We like to pin clarifications or corrections to our videos. (1) We received an excellent comment regarding the phosphate bond in ATP. So while we- and many biology sources- mention the ATP bond breakdown as an energy releasing event, this can lead to a misconception if just isolating the phosphate bond breaking alone. This is because bond breaking requires energy to be *absorbed* while bond creating *releases* energy. When we stay that when the phosphate bond in ATP breaking down (ATP hydrolysis) releases energy, we wish we had been more clear that this involves many events, including the breaking and reforming of bonds. We should clarify the entire ATP hydrolysis process itself is considered an energy releasing, exergonic process. (2) We do wish we had been more clear stating that the Krebs cycle “‘indirectly” requires oxygen” instead of just stating it “requires oxygen” —as we do not want to imply that oxygen is a reactant in the Krebs cycle (Citric Acid Cycle). While oxygen is not a reactant for the Krebs Cycle, the oxidation steps of the Krebs Cycle cannot occur without the presence of oxygen. (Thus, the Krebs Cycle is considered an aerobic process)

  3. Photosynthesis is just a process of making food but this food is only utilized when the respiration process comes into play for the production of ATP molecules, for energy purposes? If yes, then why plants release oxygen when it is needed for respiration to produce ATP? Also when this process of photosynthesis and respiration comes into play? do they operate simultaneously?

  4. Thanks for these videos, way more interesting and informative than my college professor’s lecture videos! Added bonus, I frequently find my children, 10, 4, & 2 years old, watching them with me… Little scientists in the making.
