Question

1. how are breathing and cellular respiration related?

a. inhaling brings carbon dioxide needed for cellular respiration into the body, and exhaling removes oxygen and other waste products of cellular respiration from the body.
b. inhaling brings oxygen needed for cellular respiration into the body, and exhaling removes carbon dioxide and other waste products of cellular respiration from the body.
c. inhaling brings carbon dioxide needed for cellular respiration into the body, and exhaling removes water and other waste products of cellular respiration from the body.
d. inhaling brings oxygen needed for cellular respiration into the body, and exhaling removes the energy released during cellular respiration from the body.

Explanation:

To determine the relationship between breathing and cellular respiration, we analyze each option:

• Option A: Inhaling brings oxygen (not carbon dioxide) for cellular respiration, and exhaling removes carbon dioxide (not oxygen) as a waste product. So A is incorrect.
• Option B: Breathing (inhaling) provides oxygen, which is essential for cellular respiration (the process that uses oxygen to break down glucose and produce energy, with carbon dioxide as a waste). Exhaling removes carbon dioxide and other waste products from cellular respiration. This matches the correct relationship.
• Option C: Inhaling brings oxygen, not carbon dioxide, for cellular respiration. So C is incorrect.
• Option D: Exhaling does not remove energy; energy is used or stored in the body, and exhaling removes waste like carbon dioxide. So D is incorrect.

Answer:

B. Inhaling brings oxygen needed for cellular respiration into the body, and exhaling removes carbon dioxide and other waste products of cellular respiration from the body.
