How ATP is produced in both the chloroplast and mitochondria Introduction: Living organisms use it as a free-energy donor to supply free energy for three major purposes: muscular contraction and other cellular movements, the active transport of molecules and ions, and the synthesis of proteins. ATP is not a long-term storage form of energy - is an immediate donor of energy. Most ATP is consumed within a minute ofbeing produced. The turnover of ATP is very high . ATP Generation in Mitochondria and Chloroplasts: ATP generation is driven by the electrochemical gradient of protons (the proton motive force) that exists in both mitochondria and chloroplasts. However, the mechanisms in each organelle are different when compared in detail, as will be considered later. In both chloroplasts and mitochondria the driving force behind ATP synthesis is the proton motive force that exists between two cellular compartments. This force is produced by the electrochemical...
