What is the relationship between carbon dioxide (CO\(_2\)) and oxygen (O\(_2\)) in the respiration of an orca?
A
Orcas inhale CO\(_2\) and exhale O\(_2\) during cellular respiration.
B
Orcas use both CO\(_2\) and O\(_2\) equally for energy production.
C
Orcas inhale O\(_2\) and exhale CO\(_2\) during cellular respiration.
D
Orcas do not exchange CO\(_2\) or O\(_2\) with their environment.
Verified step by step guidance1
Understand the process of cellular respiration: Cellular respiration is a biological process in which cells convert glucose (C\(_6\)H\(_{12}\)O\(_6\)) and oxygen (O\(_2\)) into energy (in the form of ATP), carbon dioxide (CO\(_2\)), and water (H\(_2\)O). This process occurs in the mitochondria of cells.
Identify the gases involved: Oxygen (O\(_2\)) is required for the process of cellular respiration to occur, as it acts as the final electron acceptor in the electron transport chain. Carbon dioxide (CO\(_2\)) is a byproduct of this process and is released as waste.
Relate this to the orca: Orcas, like all aerobic organisms, inhale oxygen (O\(_2\)) from their environment to support cellular respiration. During this process, carbon dioxide (CO\(_2\)) is produced as a waste product and is exhaled back into the environment.
Clarify the incorrect statements: Orcas do not inhale CO\(_2\) or use it for energy production. They also do not use CO\(_2\) and O\(_2\) equally, as O\(_2\) is consumed while CO\(_2\) is produced. Additionally, orcas do exchange gases (O\(_2\) and CO\(_2\)) with their environment through their respiratory system.
Conclude with the correct relationship: The correct relationship is that orcas inhale oxygen (O\(_2\)) to support cellular respiration and exhale carbon dioxide (CO\(_2\)) as a byproduct of this process.
