Answer:
A substrate-level phosphorylation
Step-by-step explanation:
Large amount of energy released in catabolic reactions is captured in ATP for use in other reactions. The conversion of ADP into ATP With transfer of phosphate from ADP without an energized membrane. This process is called substrate-level phosphorylation.
substrate-level phosphorylation is metabolic reaction in which ADP is converted to ATP by direct transfer of Phosphoryl Group (PO3) to ADP.
