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), carbon dioxide, and water.
Identify the inputs and outputs: The main inputs are glucose and oxygen, while the outputs are ATP, carbon dioxide, and water.
Focus on waste products: In cellular respiration, the waste products are substances that are not used by the cell and are expelled. These include carbon dioxide and water.
Determine the primary waste product: Carbon dioxide is considered the primary waste product because it is produced in larger quantities and is expelled from the body through the respiratory system.
Recognize the role of carbon dioxide: Carbon dioxide is produced during the Krebs cycle and the electron transport chain, and it is released as a waste product when cells generate energy from glucose.
