All living organisms require energy to perform essential functions such as movement, repair, and growth. That energy is stored in glucose - a sugar molecule produced by photosynthesis and consumed in food. Inside the cells, glucose is broken down in a process called cellular respiration, which releases usable energy in the form of ATP (adenosine triphosphate).
The overall chemical equation for cellular respiration is:
This means glucose (a food molecule) reacts with oxygen to produce carbon dioxide, water, and energy. The energy released is used for cell functions - like contracting muscles during exercise.
During physical activity, muscle cells need more energy, so the rate of cellular respiration increases. To support this, the respiratory system brings in more oxygen, and the circulatory system delivers it faster to the cells. The extra
This process shows how matter is rearranged through chemical reactions, and how energy flows from food molecules to power movement - an essential example of energy transformation in living systems.

Using Table 1 and Figure 1, describe how carbon dioxide exhaled changes with increasing activity level. Provide a pattern you observe.
Which body systems work together to increase CO
Explain why higher activity levels require more energy and how this leads to increased carbon dioxide production.
Which observation provides the strongest evidence that more cellular respiration occurs during high-intensity exercise?
Does the data support the claim that cellular respiration increases as activity level increases?
Claim:
Evidence:
Reasoning:
Compare the differences in oxygen intake and energy output between walking and jogging. What does this suggest about the relationship between oxygen use and energy production?
