Overview of Cellular Respiration Stages
This section outlines the four main stages of cellular respiration and their locations within the cell.
Definition: The four stages are glycolysis, pyruvate oxidation, Krebs cycle, and electron transport chain.
Highlight: The process generates ATP through a proton gradient and ATP synthase.
Example: Location breakdown:
- Glycolysis occurs in cytoplasm
- Pyruvate oxidation and Krebs cycle in mitochondrial matrix
- Electron transport chain in inner mitochondrial membrane

Glycolysis and Pyruvate Oxidation
This page details the process of glycolysis and subsequent pyruvate oxidation.
Definition: Glycolysis is the process of converting glucose (6C) into two pyruvate molecules (3C).
Vocabulary: Pyruvate oxidation converts pyruvate into acetyl-CoA in the mitochondrial matrix.
Highlight: Glycolysis produces 4 ATP and 2 NADH molecules.
3
of 6
Krebs Cycle Details
This section explains the Krebs cycle and its role in cellular respiration.
Definition: The Krebs cycle completes the oxidation of glucose to CO₂ in the mitochondrial matrix.
Highlight: The cycle produces electron carriers (NADH and FADH₂) for the electron transport chain.
Example: Each turn of the cycle produces one ATP molecule per pyruvate.
4
of 6
Electron Transport Chain
This page covers the electron transport chain and its role in ATP production.
Definition: The electron transport chain is a series of proteins in the inner mitochondrial membrane that generates ATP through chemiosmosis.
Highlight: This process yields approximately 36 ATP molecules from one glucose molecule.
Vocabulary: Oxidative phosphorylation is the process of ATP production using the electron transport chain.
5
of 6
ATP Production Methods
The final page explains different methods of ATP production in cellular respiration.
Definition: Chemiosmosis is the diffusion of ions across a membrane to generate ATP.
Highlight: NADH produces 2.5 ATP while FADH₂ produces 1.5 ATP through the electron transport chain.
Vocabulary: Substrate-level phosphorylation involves direct transfer of phosphate groups to ADP.

Introduction to Cellular Respiration
This page introduces the fundamental concepts of cellular respiration and its role in energy production. The process involves the catabolism of glucose to produce ATP through multiple steps.
Definition: Cellular respiration is the process of breaking down glucose to produce ATP, water, and carbon dioxide.
Vocabulary: Oxidation-reduction (redox) reactions involve the transfer of electrons between molecules.
Example: The overall equation: C₆H₁₂O₆ + 6O₂ → ATP + 6H₂O + 6CO₂ + heat
Highlight: Electron carriers NAD+ and FAD shuttle hydrogen atoms around during the process.
