The energy used by human cells requires the hydrolysis of 100 to 150 moles of ATP daily, which is around 50 to 75 kg. A human will typically use up his or her body weight of ATP over the course of the day. Each equivalent of ATP is recycled 500-750 times during a single day (100 / 0.2 = 500).

The North American tundra is located at latitudes 60Â° to 85Â° North and longitudes 55Â° to160Â° West which includes northern parts of Canada and the state of Alaska. The tundra is a cold barren wasteland that includes snow, rocks and very little variety in vegetation. It is in this place where the Arctic fox is found. The Arctic fox (Alopex lagopus) makes its home in small burrows in frost-free ground, often in low mounds, or in rock piles.
