a typical eukaryotic cell has enough available atp to meet its needs for about 30 seconds. what is likely to happen to an individual when they exhaust their atp supply?

Answers

Eukaryotic cells rely on the molecular energy of ATP to sustain all of the reactions necessary to maintain life, in the absence of ATP, these reactions would come to a halt, and the cell would inevitably die.

ATP is a molecular compound that provides the energy needed by most cells to survive. ATP represents Adenosine triphosphate, which is an organic compound that provides energy to drive the essential metabolic reactions of living cells, such as:

Muscle contractionsNerve impulsesChemical synthesisNutrient absorbtion

In the situation in which a cell was to run out of ATP, these reactions would stop, given that they require ATP to function. This means that the cell would not be able to send or receive nerve signals, absorb the nutrients it needs, or even create necessary compounds such as proteins. The stoppage of these functions would lead to the death of the cell.
