The central energy pathway which yields pyruvate,acetyl-CoA and the other intermediates that lead to these elements:
This central energy pathway includes the TCA cycle,glycolysis,Pentose-phosphate pathway and a Entner-Doudroff pathway.The Glycolysis is the conversion of glucose to pyruvate and this takes place in cytoplasm.The TCA or Krebs which is also called the citric Acid that is the complete oxidation of pyruvate to CO2 and takes place in mitochondria.Final conversion of the energy in glucose to ATP and this takes place in mitochondria.
3)The enzymes that are impaired in the absence of biotin:
The multiple carboxylase deficiencies (MCD) are genetically determined disorders of biotin metabolism, resulting in impaired activity of the four biotin dependent carboxylases.
The symptoms of this biotin deficiency is dermatitis, rash and alopecia.These symptoms are seen to be observed in nervous system, skin, respiratory system
The biotinase activity in serum was normal, indicating that this was a rare case of late-onset HCS deficiency.Multiple carboxylase deficiency (MCD) is a rare inherited metabolic disease ofbiotin dependency due to deficiency of holocarboxylase synthetase (HCS) or biotinidase deficiency.
