Supramolecular organization of tricarboxylic acid cycle enzymes
Biosystems, 1989We propose a spatial structure for the tricarboxylic acid cycle enzyme complex (tricarboxylic acid cycle metabolon). The structure is based on an analysis of data on the interaction between tricarboxylic acid cycle enzymes and the mitochondrial inner membrane, as well as on data on enzyme-enzyme interactions.

Rate parameters of the tricarboxylic acid cycle
Archives of Biochemistry and Biophysics, 1968Abstract Several aspects of the kinetic behavior of the tricarboxylic acid cycle in isolated mitochondria have been investigated. For this purpose rat heart mitochondria metabolizing pyruvate as the major substrate were incubated with succinate-1,4- 14 C (11μ m ) both in the presence and absence of added ADP.

The reactions of the tricarboxylic acid cycle in plants are very similar to those found in animals. However, because of the biosynthetic activity of the plant cell the function of the cycle is more complex than in animals, where the cycle functions principally to generate NADH to be used by the electron transport chain for ATP synthesis. In plants, the

This chapter serves as a tiepoint to intermediate metabolism in the nervous tissue. Pyruvate is chosen as the starting point for this discussion in order to cover the interconversion of three-carbon and four-carbon acids. Consequently, the acetyl-coenzyme A (acetyl-CoA, AcCoA, CoAS~Ac) pathway which contributes a two-carbon element to citrate is also ...

The History of the Tricarboxylic Acid Cycle
Perspectives in Biology and Medicine, 1970and vision? It was of course nothing ofthe kind, but a very slow evolu- tionary process, extending over some five years beginning (as far as I am involved) in 1932. At that time the problem of the intermediary stages ofthe pathways ofanaerobic energy metabolism—glycolysis and alcohol fermentation—had been established in outline by 1932, but knowledge ...

Rate control of the tricarboxylic acid cycle
Advances in Enzyme Regulation, 1970Abstract The rate of the tricarboxylic acid cycle is determined by the first step, the citrate synthase reaction. The rate of this reaction depends on the concentrations of the two substrates (oxaloacetate and acetyl-CoA) and on the activity of citrate synthase. At mitochondrial concentrations of oxaloacetate the rate of the citrate synthase reaction

Tricarboxylic Acids Cycle or Krebs Cycle
2019Krebs cycle, present in cells containing mitochondria, is described in an easily memorisable logical sequence. It is also explained why, when a patient is mechanically ventilated, care must be taken not to fall below 25 mmHg of PaCO2.
