What would happen if we couldn't carry respiration out?

There would be no energy for cellular activities

Explanation:

Cellular respiration is the process whereby living organisms breakdown ingested food in their cells in order to obtain energy in form of ATP. In other words, respiration converts the stores energy in food molecules into usable energy by the cell. The general equation of the process is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O

The process of cellular respiration is carried out by every living organism in order to obtain energy to perform their various metabolic activities. Hence, without RESPIRATION, there would be no energy (ATP) for use by the cell, which utterly means no cellular activities will take place.
