Adenosine triphosphate bioenergetics

A remarkable feature of the bioenergetic oxidation reactions of nutrients in cells is the fact that they are always coupled to another reaction, that of synthesis of the energy-rich chemical substance adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and phosphate (oxidative phosphorylation Engelgardt and Ljubimova, 1939) ... 

Ozone has been shown to initiate many physiological and biochemical changes in sensitive plant species. Decreases in photosynthesis and increases and decreases in respiration have occurred in response to ozonation. The bioenergetic status of mitochondria and chloroplasts is disturbed by ozone. Decreases in oxidative- and photo- phosphorylation have been reported as have increases in adenosine triphosphate and total adenylate content of plant tissue. The variable physiological responses appear to be related to the stage of symptom development at the time of analysis and to the mode of ozone exposure, viz. in vivo and in vitro. 

The study of bioenergetics deals with energy formation and utilization in living systems. In most living cells energy is found in the form of adenosine triphosphate (ATP). Many biochemists believe that the cell is regulated, at least in... 

Ion-binding studies with biological molecules can be important in elucidating fundamental biochemical reaction systems in relation to bioenergetics, enzyme activation and membrane transport [182]. For example, the adenosine triphosphate (ATP)—adenosine diphosphate (ADP) cycle is one of the processes of primary importance to cellular energy systems and association constants determined [427—430] for metal—ATP and metal—ADP complexes are therefore of considerable interest Table 2.5). The constants may be obtained from measure-... 

Severe Ochoa began his career as a biochemist not long after the discovery of the importance of the pyrophosphate bond in energy transduction. Lohmann, working in the laboratory of Severn s teacher Otto Meyerhof, discovered in 1929 what we now know as the central compound of bioenergetics—adenosine triphosphate. ...
