    i am struggling to answer these two questions.
    a) Why would a mutation that abolished the activity of Triose Phosphate Isomerase prevent a mirco-organism growing anaerobically using the glycolytic pathway to metabolise glucose to pyruvate as a sole energy source?
    kindly check the glycolytic pathway on the internet as i cant post it here.
    b) In strenuously exercising muscle the enzyme Lactate dehydrogenase catalyses
    the following reaction:
    Pyruvate + NADH + H+ → Lactate + NAD+
    What is the physiological function for this reaction?
    answer: for the part b it can be that the reduction of pyruvate to lactate re-generates NAD+ from NADH - allowing glycolysis to continue. but what else should i include.

    Any help would be very appreciated.
