Question

The energy consumed during the conversion of ADP into ATP is
A. 73000 cal/mole
B. 686000 cal/mole
C. 8000 cal/mole
D. 7300 cal/mole

Answer 1

Hint: The conversion form of ATP from ADP is as follows:

Complete answer: Adenosine triphosphate or ATP is a derivative of adenine ring, pentose sugar i.e. ribose, and three phosphate groups.
Adenosine diphosphate or ADP is a derivative of adenine ring, pentose sugar i.e. ribose, and two phosphate groups.
ATP is synthesized in the body by an electron transport chain or ETC with the help of an enzyme called ATP synthase.
Hydrolysis of ATP produces one molecule of ADP and an inorganic phosphate.
Further, upon hydrolysis, one molecule of ADP gives rise to one molecule of AMP or Adenosine monophosphate and one pyrophosphate.
AMP contains an adenine ring, a pentose sugar i.e. ribose, and a phosphate group.
Hydrolysis of ATP generates 7300 calories of energy per mole.

Additional information: 1. ATP is the energy currency of our bodies.
2. ETC takes place in the inner mitochondrial membrane.
3. ATP is a very high energy-yielding molecule.
4. ATP helps to do all the activities that are performed by a human body.
5. It helps in the metabolism, as well as all the chemical reactions that take place inside the body.

So, the correct answer is option D. 7300 cal/mole.

Note: ATP is a nucleotide that is used as a coenzyme inside the cells. ATP is called the "molecular unit of currency". ATP helps to transport chemical energy within cells that are used for metabolism. Every cell uses ATP as energy for functioning.
As the name suggests, ATP is made up of an adenine nitrogen base and three phosphate groups.
