Question

20. Which of the following describes the relationship between the respiratory system and cellular respiration?

A. The respiratory system provides a reactant and removes a by-product of cellular respiration.
B. The respiratory system generates enzymes used during cellular respiration.
C. The respiratory system transports oxygen to body cells performing cellular respiration.
D. The respiratory system removes carbon dioxide from body cells performing cellular respiration.

Answer 1

The correct answer is option D: The respiratory system removes carbon dioxide from the body's cells that perform cellular respiration.

Step-by-step explanation:

Hello!

Let's solve this!

The correct answer is option D: The respiratory system removes carbon dioxide from the body's cells that perform cellular respiration.

Oxygenated blood transports oxygen to the cells that need it to function. Also, by means of blood, it eliminates the carbon dioxide that is generated as waste in cellular respiration.

Answer 2

Cellular respiration is when the cells in your body make use of ATP and produce by-products.

The correct answer is:
D. The respiratory system removes carbon dioxide from body cells performing cellular respiration.

It isn't C because the lungs don't transport oxygen to cells. It transports oxygenated blood back to the heart where it is pumped through the body.
