Verified step by step guidance

Understand the purpose of cellular respiration: Cellular respiration is a metabolic process that converts biochemical energy from nutrients into adenosine triphosphate (ATP), and then releases waste products.

Identify the main substrates and products: The primary substrate for cellular respiration is glucose, and the main products are ATP, carbon dioxide (CO2), and water (H2O).

Recognize the stages of cellular respiration: Cellular respiration consists of glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain). Each stage contributes to the production of ATP.

Clarify the role of ATP: ATP is the energy currency of the cell, used to power various cellular processes. The main function of cellular respiration is to produce ATP from glucose.

Conclude the function: Based on the understanding of cellular respiration, its primary function is to extract usable energy from glucose in the form of ATP, rather than reducing CO2, extracting CO2, synthesizing macromolecules, or producing carbohydrates.
