How does respiration fulfil the energy requirement of an organism?

Open in App

Solution

The energy released during cellular respiration is immediately used to synthesise a molecule called ATP which is used to fuel all other activities in the cell. In these processes, ATP is broken down giving rise to a fixed amount of energy which can drive the endothermic reactions taking place in the cell.
hence, the energy requirement of an organism is fulfilled.
