Document Summary
The regulation of anabolic pathways in regards to feedback ( gene ) expression, that is to mean: The regulation of protein activity ie feedback inhibition. How gene expression regulation differs in eukaryotes and prokaryotes with the help of. Metabolic pathways are involved in the biosynthesis of essential molecules such as a. a and carbs etc. Bacteria regulate the activity of these pathways by : Stopping the synthesis of these molecules if they are readily available. Also, the very presence of end product often represses the pathway. Feedback inhibition ( involves suppression of protein activity) Feedback repression ( invovles repression of gene expression) these 2 might sound the same but they are 2 different things. Where the product of a pathway inhibits the activity of an enzyme earlier in the pathway often the end product of the pathway will allosterically bind to an enzyme, usually an allosteric.
