Question

based on the model in figure 1, how are the lower oxygen levels in denver causing the students to struggle more during their workouts and breathe more heavily?
a. the students are not storing enough oxygen, which is used as energy.
b. the students inhale less oxygen with each breath, which causes them to exhale less carbon dioxide.
c. the students inhale less oxygen with each breath, which reduces their production of atp.
d. the students are not storing enough oxygen, which increases their production of atp.

Explanation:

Oxygen is crucial for cellular respiration to produce ATP, the energy - currency of the cell. In lower oxygen levels, less oxygen is inhaled per breath, reducing ATP production, which can cause students to struggle during workouts. Oxygen is not stored as energy directly (A is incorrect), and the focus here is on ATP production rather than carbon - dioxide exhalation (B is incorrect). Also, less oxygen leads to less, not more, ATP production (D is incorrect).

Answer:

C. The students inhale less oxygen with each breath, which reduces their production of ATP.
