Multiple Choice
In the context of cellular respiration in sea urchins, what is the relationship between carbon dioxide (CO\(_2\)) and oxygen (O\(_2\))?
A
Neither O\(_2\) nor CO\(_2\) are involved in cellular respiration.
B
Both O\(_2\) and CO\(_2\) are produced during cellular respiration.
C
O\(_2\) is consumed and CO\(_2\) is produced as a result of cellular respiration.
D
CO\(_2\) is consumed and O\(_2\) is produced during cellular respiration.

Cellular respiration is a metabolic process that occurs in the mitochondria of cells, where glucose (C₆H₁₂O₆) is broken down to produce energy in the form of ATP (adenosine triphosphate).
During cellular respiration, oxygen (O₂) is consumed as the final electron acceptor in the electron transport chain. This is a critical step for the production of ATP.
Carbon dioxide (CO₂) is produced as a byproduct during the breakdown of glucose in the citric acid cycle (also known as the Krebs cycle). This occurs when carbon atoms from glucose are released as CO₂ molecules.
The overall chemical equation for cellular respiration can be summarized as: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP). This equation shows that O₂ is consumed and CO₂ is produced.
In the context of sea urchins, as in other organisms, O₂ is consumed and CO₂ is produced during cellular respiration. This process is essential for generating the energy required for cellular functions.
