Question

One of the primary waste products of normal cellular metabolism that must be removed from the body by the lungs is: Select one: a. pyruvic acid. b. carbon monoxide. c. lactic acid. d. carbon dioxide.

Answer 1

Answer:D

Explanation:

Cellular metabolism involves series of orderly sequences of controlled biochemical reactions, in which organisms convert biochemical energy from food nutrients into ATP energy currency of the cell and then release waste products.

Cellular respiration is a process where carbohydrates are broken down to release energy for cellular activities and CO2 is released as byproduct.

Animals breath in oxygen and exhale carbon dioxide a byproduct of cellular respiration.

Chemical equation 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
