Newborn infant prevents hypothermia by: (A) Coupling of oxidation with phosphorylration, (B) Uncoupling of oxygenation with phosphorylation, (C) Non - shivering theromgenesis, (D) Shivering thermogenesis
Answer is C. Normally, Oxidation occurs
↓
Energy generated in used for ATP production by phosphorylation
This is known as Coupling of oxidation with phosphorylation.
In Newborn: Due to Brown fat,
Energy generated from oxidation is used for heat production not ATP production to prevent hypothermia.
This Mechanism is Non - shivering thermogenesis or Uncoupling of oxidation with phosphorylation.
