Which enzyme helps to put bond a phosphate back to ADP to make it ATP? Lenase
ATP Synthase
ATM Synthase

ATP Synthase

Explanation:

An enzyme called ATP synthase is embedded in the inner mitochondrial membrane. The protons diffuse through the ATP synthase, which uses the energy from the proton motive force to add a phosphate group to ADP molecules available in the matrix inside the inner membrane.
