The synthesis of atp from adp and pi is a(n) reaction with δg. endergonic; a negative exergonic; a positive endergonic; a positive exergonic; a negative reversible; zero

The entire process of manufacturing energy is known as oxidative phosphorylation, which takes place in the mitochondria, where ATP synthase enzyme is situated in the inner mitochondrial membrane and the F1-component protrudes into the mitochondrial matrix.  

In the process, ADP combines with a phosphate to produce ATP. The energy liberated due to the hydrolysis of ATP into ADP is utilized to do cellular function, generally by coupling the exergonic reaction of the hydrolysis of ATP with the endergonic reactions.  

The synthesis of ATP from ADP and Pi is an endergonic reaction with positive delta G.

he is very short, and he can only reach halfway up on the elevator buttons. but on a rainy day, he has his umbrella with him, and he uses it to poke the button at the top.
