What is the difference between ATP synthase and ATPase, and how do their functions differ in cellular energy production?

ATP synthase is an enzyme that produces ATP from ADP and inorganic phosphate during cellular respiration. ATPase, on the other hand, is an enzyme that hydrolyzes ATP to ADP and inorganic phosphate to release energy. While ATP synthase helps generate ATP for cellular energy, ATPase helps break down ATP to release energy for cellular processes.
