Chemiosmosis The actual production of ATP in cellular respiration takes place through the process of  chemiosmosis. Chemiosmosis involves the pumping of protons through special  channels in the membranes of mitochondria from the inner to the outer compartment.  The pumping establishes a proton gradient. After the gradient is established, protons  pass down the gradient through particles designated F1. In these particles, the energy  of the protons generates ATP, using ADP and phosphate ions as the starting points. The energy production of cellular respiration is substantial. Most biochemists agree that  36 molecules of ATP can be produced for each glucose molecule during cellular

Unformatted text preview: respiration as a result of the Krebs cycle reactions, the electron transport system, and chemiosmosis. Also, two ATP molecules are produced through glycolysis, so the grand total is 38 molecules of ATP. These ATP molecules may then be used in the cell for its needs. However, the ATP molecules cannot be stored for long periods of time, so cellular respiration must constantly continue in order to regenerate the ATP molecules as they are used. Each ATP molecule is capable of releasing 7.3 kilocalories of energy per mole....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
