Chapter 9, Problem 3
After glucose is fully oxidized by glycolysis, pyruvate processing, and the citric acid cycle, where is most of its energy stored?
Verified step by step guidance1
Understand the process of glucose oxidation: Glucose is broken down through glycolysis, pyruvate processing, and the citric acid cycle. Each of these steps contributes to the conversion of glucose into energy.
Identify the main products of glycolysis: Glycolysis converts glucose into pyruvate, producing a small amount of ATP and NADH in the process.
Recognize the role of pyruvate processing: Pyruvate is further processed to form acetyl-CoA, which also generates NADH.
Examine the outcomes of the citric acid cycle: Acetyl-CoA enters the citric acid cycle, resulting in the production of ATP, NADH, and FADH2.
Determine the primary energy storage molecules: Most of the energy from glucose oxidation is stored in the high-energy electron carriers, NADH and FADH2, which are utilized in the electron transport chain to produce a significant amount of ATP.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Glycolysis
Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH in the process. This occurs in the cytoplasm and is the first step in cellular respiration, setting the stage for further energy extraction from glucose.

Glycolysis
Citric Acid Cycle
The citric acid cycle, also known as the Krebs cycle, takes place in the mitochondria and processes acetyl-CoA derived from pyruvate. It generates high-energy electron carriers, NADH and FADH2, which are crucial for the next stage of cellular respiration, contributing to the majority of energy storage from glucose oxidation.

Oxidative Phosphorylation
Oxidative phosphorylation is the final stage of cellular respiration, occurring in the inner mitochondrial membrane. It utilizes the electrons from NADH and FADH2 to create a proton gradient, driving ATP synthesis through ATP synthase. Most of the energy from glucose oxidation is stored in the form of ATP produced during this process.
