Final answer:
The human body's energy system, known as energy metabolism, captures energy from rescue workers' bodies to power equipment during rescue missions. This system relies on the conversion of food into usable energy through cellular respiration and the production of ATP, which is used to power muscle contractions.
Step-by-step explanation:
The energy system that captures energy from rescue workers' bodies to power equipment during rescue missions is known as the human body's energy metabolism. The primary source of energy for the body is food, which is converted into usable energy through cellular respiration. Specifically, the body breaks down glucose molecules in the presence of oxygen to produce adenosine triphosphate (ATP), the main energy currency of cells.
During physical activities, the body's energy demands increase, requiring more ATP production. This is achieved by breaking down stored glycogen (a form of glucose) or fatty acids through various metabolic pathways. ATP is then used to power muscle contractions, allowing rescue workers to perform their tasks.
Overall, the human body's energy system relies on the conversion of chemical energy in food into useful work through cellular respiration and ATP production.
