Formation of ATP in Plants Adenine tri-phosphate, known as ATP, is the universal currency of energy in all living organisms. It was first isolated in the early 1930s, having been extracted from muscle tissue. In plant cells, ATP is needed for both respiration and photosynthesis, and is formed during different processes. In respiration, organic molecules act as fuel. These are broken down in a series of reactions, and chemical potential energy is used to synthesise ATP. The synthesis of ATP involves attaching a phosphate group to ADP. The energy needed for this comes from the oxidation of glucose. The breakdown of glucose can be split into two parts, glycolysis and the Krebs cycle. In glycolysis, the hexose sugar is converted into pyruvate, which has three carbon atoms. This leads to dehydrogenation, when two hydrogen atoms are removed from the triose by a dehydrogenase enzyme. These hydrogen atoms are taken...
