Question

Nepalese Sherpas underwent a mutation that allows them to burn fat instead of glucose to maximize oxygen delivery at high altitudes. TRUE OR FALSE?

Answer 1

Ans) False

Explaination: The statement is false because oxidation of fat for energy supplies required more oxygen amount as compare to glucose and at high altitudes there is scarcity of oxygen so this statement is false.

Nepalese Sherpas are capable or highly efficient mountain climbers because their mitochondria in muscle cell were less leaky which made then able to produce more energy from less oxygen as compare to  other peoples .Sherpas also have ability to produce energy even without oxygen through anerobic metabolism. Nepalese Sherpas have adapted to low oxygen amount at high altitudes  over  hundreds of generations which leads to their better survival in oxygeb deprivation condition as compare to people of other areas.
