He typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. the available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate for about one day. after the reserve has been depleted during starvation, how would the body obtain more glucose?

Oxidation of body fatty acids

Explanation:

Once energy reserve has been depleted during starvation, the body switches to FAT OXIDATION.

The oxidation of long chain fatty acids to acetyl-CoA is a central energy-yielding pathway.

The acetyl-CoA generated enters the CITRIC ACID CYCLE and finally the ELECTRON TRANSPORT SYSTEM yielding ENERGY in form of ATP.

So, during starvation energy utilization switches TO oxidation of fatty acids.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
