Comment on the statement – Respiration is an energy producing process but ATP is being used in some steps of the process.

Although respiration is an energy producing process but ATP is also being used in some steps of the process. For example, the phosphorylation reactions in the glycolysis process in which glucose is converted to glucose – 6 – phosphate which consumes one ATP.

Although the overall ATP produced by the complete oxidation of the substrate is more than the amount of energy spent on some metabolic processes.
