Question

1. asthma is a condition in which it can be very hard for a person to breathe in enough air. would it also be difficult for someone with asthma to exercise?

a no, as long as the person is getting enough sleep, he will make enough energy to exercise.

b no, as long as the persons cells are getting different types of molecules from food, he can still exercise.

c no, the persons cells may not have everything they need, but his body can still exercise normally.

d yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.

Explanation:

When exercising, the body's demand for oxygen ($O_2$) increases. Asthma causes airway constriction, reducing the amount of air (and thus $O_2$) that can enter the lungs. Cells need $O_2$ (from air) for cellular respiration to produce energy ($ATP$) required for muscle contraction during exercise. Options a, b, and c ignore the critical role of oxygen from air for cellular function during exercise.

Answer:

d. Yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.
