Peter Mitchell showed the discovery of how mitochondria converts energy in glucose into ATP. Adenosine triphosphate, or ATP for short, is the energy currency of life. ATP is a high-energy molecule found in every cell. Its job is to store and supply the cell with needed energy to do energy-required work. He worked on his research about how mitochondria converts energy into glucose in his own research laboratories in a renovated country house in rural Cornwall, in which the concept was controversial for more than twenty years.
Peter Mitchell finally proved that mitochondria converts energy into glucose in 1978 which he then won the Nobel Prize for Chemistry on the following year for his discovery of the chemiosmotic mechanism of ATP synthesis. Chemiosmosis is the movement of ions across a semipermeable membrane, down their electrochemical gradient, Peter Mitchell proved that chemiosmosis also occurs during cellular respiration or photosynthesis, in which the generation of adenosine triphosphate (ATP) by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis.The reason why Peter Mitchell proved that Chemiosmosis occurs during cellular respiration is because he wanted to find the reason about why Both Cell Respiration, occurring in the mitochondria, and the light reactions of photosynthesis, occurring in the chloroplasts which make ATP but no one understood how this occurred as no intermediate substrate molecule bearing the phosphates groups was known.Phosphates are a biological molecule composed of phosphorus and oxygen which played a major role in biological processes in many organisms such as the ATP in mitochondria. Mitchell then determined that the power to make ATP came from two processes linked indirectly. He used the formulation of chemiosmosis to understand how biological energy transfer (ATP). ATP, which is a nucleotide is known as “the energy currency of life” as it is the high-energy molecule which stores energy we use all the time. Perhaps the strongest support for the chemiosmotic hypothesis comes through from many experimentation, beginning with an experiment using chloroplasts.
