If a cell lost its ability to perform cellular respiration then after some time the cell will eventually die.
Explanation;
Cellular respiration is the process which takes in nutrients and uses them to create energy in the form of ATP, which is used by the cells to perform their activities. Therefore; the main purpose of cellular respiration is the provision of energy to the cells which they need to function. Therefore; if a cell lost its ability to undertake cellular respiration, it means that energy wont be generated , and thus, cellular activities will not take place and hence the cell will die.
