engaging warm up discussion
think about it for a minute before answering the 2 questions below in complete sentences:
what do you think it means when we say we are \burning calories\ ... and are we actually \burning\ something?
remember what you learned about cellular respiration (breathing) from biology. how do you think this might be related to \burning calories\?

Explanation:

When we say "burning calories", it refers to the process of cellular respiration in our bodies. In cellular respiration, glucose and oxygen are used to produce energy in the form of ATP, carbon - dioxide, and water. It's like a controlled "burning" of nutrients (such as glucose) to release energy for our body's functions. Just as a fire burns fuel to release heat and light, our cells "burn" nutrients to release energy for activities like movement, thinking, and maintaining body temperature.

Answer:

When we say "burning calories", we mean the body is breaking down nutrients through cellular respiration to release energy. We are not actually burning in the same sense as a fire, but rather undergoing a chemical process to extract energy from food. Cellular respiration is related to "burning calories" because it is the biochemical process by which our cells convert the chemical energy stored in nutrients (calories) into usable energy (ATP).
