Answer:
Glucose
Respiration
Oxygen
Explanation:
Cellular respiration can be shown with this word equation:
glucose + oxygen => water vapour + carbon dioxide + ATP energy
Our body uses cellular respiration to produce the energy our cells need for us to survive.
We get glucose from the food we eat, especially carbohydrates.
In this process, oxygen breaks down glucose (food) to produce ATP energy.
