Question

What is meant by the term metabolic flux, and how is it regulated?

Answer 1

Metabolic thux refers to the amount of a Metabolité processed by one or more catalytic steps per unt time, and it is typically vornalised by cellular abundance (eg. gram dry weight). Flux confred refers how to changes in the abundance or activity of a beological species usually an enzymes empact metabolic flus through a pathway or system. - Flux is regulated by the enzyme nurowed in a pathway. Within cells, regulations of flux ! is vital for all metabolic pathways to regulate the pathway's activity ander different conditions. The enzymatic regulation may be Indireet, in the case of an enzyme being regulated by some cell signalling mechanison (one phosphorylation), or it may be direet as in case of a allosteric regulation, where Metabolites from a different portion of a metabolic altwork bind directly to and affect the catalytic function of other en reynes in order to maintain homeostasis. 00
