Question

During respiration, members of the animal kingdom use ______ and then release ______ as a waste gas.

A) oxygen:hydrogen
Eliminate
B) carbon dioxide:oxygen
C) oxygen:carbon dioxide
D) carbon dioxide:water vapor

Answer 1

C

Step-by-step explanation:

Let's look at the cellular respiration equation

oxygen+glucose--> water + carbon dioxide + ATP

In the process, oxygen is used. We inhale oxygen and use it in cellular respiration. We then create carbon dioxide which is exhaled out. We don't use the carbon dioxide, so it is the waste product.

Therefore, the answer is C. Oxygen is used, and carbon dioxide is released as waste.
