Food contains organic molecules such as ; energy is released when cells break down this molecule.

The correct answer will be-glucose molecules

Explanation:

The food contains all the molecules which provide the energy to the cell through the process of slow oxidation called cellular respiration.  The respiration provides energy to the cell by breaking down the food particles which provides the substrate like glucose and proteins.

The glucose is used as the major substrate as the cellular respiration breaks down the glucose molecule through glycolysis which is followed by the Citric acid cycle and electron transport chain.

Thus, glucose molecules are the correct answer.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
