Energy Metabolism during Apoptosis

Energy metabolism during mammalian embryogenesis

would suggest that the enzyme responsible for mediumchain fatty acid activation is not active at this time. The lack of antagonism of salicylate and octanoate against the embryotoxic effects of valproate is also compatible with the mechanisms of teratogenicity and hepatotoxicity being fundamentally different. Although these data rule out one possibility, they provide little direct information o...

Promotion of mitochondrial energy metabolism during hepatocyte apoptosis in a rat model of acute liver failure

Hepatocyte apoptosis and energy metabolism in mitochondria have an important role in the mechanism of acute liver failure (ALF). However, data on the association between apoptosis and the energy metabolism of hepatocytes are lacking. The current study assessed the activity of several key enzymes in mitochondria during ALF, including citrate synthase (CS), carnitine palmitoyltransferase‑1 (CPT‑1...

Cellular Energy Metabolism during Fetal Development

In view of the importance of fatty acids as substrates for the mature heart, fatty acid oxidation by fetal and calf heart mitochondria has been investigated. Free fatty acids of 10 carbon units or less which exhibit carnitine-independent transport into mitochondria were effective substrates for oxidative phosphorylation in both fetal and calf heart mitochondria. Efficient oxidative phosphorylat...

Energy metabolism of human neutrophils during phagocytosis.

Detailed quantitative studies were performed on the generation and utilization of energy by resting and phagocytosing human neutrophils. The ATP content was 1.9 fmol/cell, was constant during rest, and was not influenced by the presence or absence of glucose in the medium. The intracellular content of phosphocreatine was less than 0.2 fmol/cell. In the presence of glucose, ATP was generated alm...
