A. An enzyme passes a high-energyphosphate to ADP, resulting in ATP, best defines substrate level ATP synthesis.Enzymes are the catalysts that facilitate this process by transferring phosphates from a substrate to ADP, producing ATP. The process involves the use of high-energy phosphates, such as phosphoenolpyruvate, which is a product of glycolysis. This type of ATPsynthesisis known as substrate-level phosphorylation and is a key step in energy production in cells. Phosphates are important in this process as they provide the energy needed forATPsynthesis.Therefore, the correct answer is A.To know more aboutenzymesvisit :-brainly.com/question/14577353#SPJ11...
