Why does cells that carry out a lot of active transport often have many mitochondria?

In active transport particles move against a concentration gradient and therefore require energy which must be supplied by the cell.

Explanation:

In active transport, particles move against a concentration gradient and therefore require energy which must be supplied by the cell with the mitochondria, which is why there is a lot of it.

Explanation:

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.  

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
