Question

1. using the formula for cellular respiration and what you know about sugar and atp, explain how exercise creates more co2.

Explanation:

Exercise increases energy demand, so cells speed up cellular respiration: $\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{ATP}$. More glucose is broken down, producing more $\text{CO}_2$ as a waste product.

Answer:

Exercise raises ATP demand, accelerating cellular respiration which generates $\text{CO}_2$ as a byproduct, thus increasing $\text{CO}_2$ output.
