Here are the answers to your questions:

**Question 1:** The molecule that is broken down during cellular respiration is **sugar**.

**Question 2:** When pyruvic acid is created during cellular respiration, in addition to the four total ATP produced, **heat** is also produced as a result of this reaction.

**Question 3:** Hydrogen bonds tightly to oxygen during cellular respiration because **it is less electronegative than oxygen**.

**Question 4:** The byproduct of lactic acid fermentation is **lactic acid**.

**Question 5:** When a reaction releases more energy than it uses, it is called **exothermic**.
