Comment on the statement respiration is an energy producing process but ATP is being used in somesteps of the process.
Respiration is necessary catabolic process which occurs in stepwise to produce energy. Whenever biological system requires energy it is provided by hydrolysis of ATP molecule.
When one ATP is hydrolysed to ADP + Pi, i.e., one phosphate bond is broken down, thus producing 73 kcal energy.
Thus, ATP is utilised only when it is required so as to maintain the respiratory balance sheet.
