Question
This question has two parts.
A professional athlete often runs long distances. Some of the steps that enable the athlete to run are shown.
Step 1: The athlete eats food before running.
Step 2: The food is broken down into nutrients.
Step 3: Usable energy is produced from the nutrients.
Step 4: The athlete’s muscles use the energy to contract.

As the athlete runs, the amount of
and
in the body decreases as cells make
. At the same time the amount of
produced by the body increases because it is a product of cellular respiration.

**Part A**
The following provides a more accurate step than the ones shown:
**Step 3:** Usable energy is produced from the nutrients during cellular respiration.
This step accurately describes the process by which energy is extracted from nutrients.
**Part B**
As the athlete runs, the amount of **oxygen** and **glucose** in the body decreases as cells make **ATP** (adenosine triphosphate). At the same time, the amount of **carbon dioxide** produced by the body increases because it is a product of cellular respiration.
