Which of the following can be compared to a fully charged battery?
A
ADP
B
ATP
C
Adenosine
D
Ribose
Explanation: 

Detailed explanation-1: -The ATP molecule is just like a rechargeable battery. When it’s fully charged, it’s ATP.

Detailed explanation-2: -Adenosine 5’-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.

Detailed explanation-3: -Much like a rechargeable battery with a fluctuating state of charge, ATP represents a fully charged battery, and ADP represents “low-power mode.” Every time a fully charged ATP molecule loses a phosphate bond, it becomes ADP; energy is released via the process of ATP becoming ADP.

Detailed explanation-4: -An ATP molecule, shown in the Figure below, is like a rechargeable battery: its energy can be used by the cell when it breaks apart into ADP (adenosine diphosphate) and phosphate, and then the “worn-out battery” ADP can be recharged using new energy to attach a new phosphate and rebuild ATP.
