Verified step by step guidance1
Understand the process of cellular respiration: Cellular respiration is a metabolic process that converts glucose and oxygen into energy (ATP), water, and carbon dioxide.
Identify the inputs and outputs: The main inputs are glucose and oxygen, while the outputs are ATP, water, and carbon dioxide.
Focus on waste products: In cellular respiration, the primary waste product is carbon dioxide, which is expelled from the body during exhalation.
Consider the role of carbon dioxide: Carbon dioxide is produced during the Krebs cycle and the electron transport chain as glucose is broken down.
Review the options given: Among the options provided (Oxygen, Water, Carbon dioxide, Glucose), carbon dioxide is the correct answer as the primary waste product of cellular respiration.
