    You are investigating the biochemical origins of cow methane emissions (belches and farts, to be blunt) which contribute to global warming.

    Bacteria in the cow gut make methane and a key enzyme in the pathway is methyl-coenzyme M reductase. The turnover number of pure enzyme (mass 300 kDa) is 100 s-1. What is the specific activity of the enzyme in µmol.min-1.mg-1?

    A cow typically 'emits' 100 L of methane gas a day. Given the concentration of methane in this gas is 0.05 M, how many mg of this enzyme does the cow gut contain?

    Solution Summary

    Cow methane emissions (belches and farts) which contribute to global warming are caused by the methyl coenzyme M reductase. Bacteria in the cow gut make methane with the help of this key enzyme. This solution discusses these concepts further.
