Which one of the following biotransformations provides maximum energy to human body?

ADP-AMP
ATP-ADP
ADP-ATP
AMP-ADP

The correct answer is (b), ATP-ADP.

ATP (adenosine triphosphate) is a molecule that stores energy in its chemical bonds. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, it releases energy that can be used by the body. This process is called hydrolysis.

The hydrolysis of ATP is a reversible reaction, which means that it can go in either direction. When the body needs energy, it can break down ATP to ADP and inorganic phosphate. When the body has excess energy, it can use that energy to resynthesize ATP from ADP and inorganic phosphate.

The hydrolysis of ATP is the main source of energy for the human body. It is used to power all of the body’s cells, including muscle cells, nerve cells, and brain cells.

The other options are incorrect because they do not involve the hydrolysis of ATP. Option (a), ADP-AMP, is the reverse of the hydrolysis of ATP. Option (c), ADP-ATP, is simply the resynthesis of ATP from ADP and inorganic phosphate. Option (d), AMP-ADP, is the conversion of AMP (adenosine monophosphate) to ADP.

I hope this explanation is helpful!
