Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What gas is released into the air during cellular respiration?
A
oxygen
B
carbon dioxide
C
water
D
glucose
Explanation: 

Detailed explanation-1: -During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.

Detailed explanation-2: -Ingested nutrients in the form of glucose ( C 6 H 12 O 6 ) and oxygen are converted to energy in the form of adenosine triphosphate through cellular respiration (ATP). As a result of this reaction, CO 2 is created as a byproduct. Inhalation provides the oxygen required for cellular respiration.
