You consume food, and your body converts that food energy to the main energy currency used for cell, called glucose Two of the breakdown products of this main energy source are a phosphate group and ATP can only fuel your cells for 2-4 seconds. If there were no resupply of ATP available, another high-energy compound called can be quickly broken down lo release enough energy to make more ATP When muscle cells ATP from ADP and PCr, the byproduct is

Solution

1. ATP is the primary energy currency of cell, and of life, because it is the energy molecule that all cells need in order to do anything within the human body.

2. ADP

3. Glucose

4. phosphocreatine (PCr)
