Homework Help: Metabolic pathways problems

  1. Dec 31, 2007 #1
    1. The problem statement, all variables and given/known data
    The questions i'v been given are

    1. With the aid of a diagram, describe the mechanism of CUMULATIVE feedback regulation in branched metabolic pathways. (5 marks)

    2. Explain how the use of iso-enzymes allows cells to regulate metabolic pathways using feedback mechanisms. (5 marks)

    Basically i don't really understand what the diagrams actually are and therefore can't really describe them. These are the notes i'v been given and i can't seem to find any other information/diagrams similar to these anywhere on the internet. These questions are from a past paper so unfortunately there is no mark scheme! If anyone could just explain how best to answer these questions i'd be extremely grateful. Thanks in advance

    PS. PDF file of notes is attached.
