Question
Your body is indirectly fueled by food, but, like other cells, muscle cells cannot directly use the energy released from breaking down glucose or triglycerides. Complete the sentences about energy sources for exercising muscles with the appropriate term. You consume food, and your body converts that food energy to the main energy currency used for cells, called _____. 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 to release enough energy to make more ATP. When muscle cells enzymatically reform ATP from ADP and PCr, the byproduct is _____.Explanation / Answer
You consume food and your body converts that food energy to the main energy currency used by cells, called ATP(Adenosine triphosphate).
Two of the breakdown products of this main energy source are a phosphate group and Adenosine diphosphate
ATP can only fuel your cells for 2-4 seconds. If there is no resupply of ATP available, another high energy-rich compound called phosphocreatine (PCr) can be quickly broken down to release enough energy to make more ATP.
When muscle cells enzymatically reform ATP from ADP and PCr, the by-product is creatinine.
Thus a brief explanation of the above situation is the fact that, during exercise the ADP levels go high this favors resynthesis of ATP. The breakdown of Phosphocreatine leads to this resynthesis.
