Base metabolism diverges from Mass as the Universitat de València the Universidad Politécnica de Madrid y and the Queen Mary University of London have been successfully solved the puzzle that had perplexed biologists for over a century. How and why an organism’s base metabolism differs being resultant from its mass. Base metabolism signifies is the minimal energy that an organism requires to exist.

An adult body in total rest at a 20º C room temperature devours around one calorie or kilo but an elephant burns half a calorie per kilo of mass in the same span of time, while a mouse burns a staggering 70 calories per kilo. What propels this difference?

German physiologist Max Rubner, while studying the base metabolism of different size dogs in 1883, was one of the handfuls of people who contemplated this occurrence. Rubner indicated that the occurrence of this phenomenon could be attributed towards the heat lost through skin. The surface of the skin differs according to a size of the animal squared, but its volume differs by the size cubed, which was indicative of the fact that base metabolism B varies proportionately to the mass raised to the power of 2/3, M2/3. But in 1932, quantification that Swiss biologist Max Kleiber enacted for mammals of a wider range of masses, including oxen and rats which signified that alterations in metabolism followed M3/4, a figure we now know as Kleiber’s law. The exploration for an explanation to this figure triggered a deep discussion for decades which came to its culmination in 1997 with the fractal model of physicist Geoffrey West.
