In connection with the tryptophan operon, that an excess of tryptophan can cause a repression of the genes of this operon, leading to an arrest of the synthesis of the enzymes required for the formation of tryptophan. Beside this possibility of repression, there is very often feedback inhibition, i.e. the possibility for an essential metabolite (amino acid, nucleotide, etc.), which [...]
The following points highlight the top four stages for reregulation of carbohydrate metabolism. The stages are: 1. Regulation of Carbohydrate Metabolism at the Cellular and Enzymatic Level 2. Regulation of Glycolysis, Gluconeo-Genesis and Hexose Monophosphate Shunt 3. Regulation of Glycogen Metabolism 4. Regulation of the Citric Acid Cycle. Stages for Regulation of Carbohydrate Metabolism: Contents: Regulation of Carbohydrate Metabolism at [...]
The following points highlight the top two stages for regulation of lipid metabolism. The stages are: 1. Regulation of Lipogenesis 2. Regulation of Ketogenesis. Regulation of Lipogenesis: a. Lipogenesis is concerned with the conversion of glucose and intermediate such as pyruvate, lactate and acetyl-CoA to fat. b. The rate of lipogenesis is high in case of a diet containing a [...]
