2. ATP (Adenosine Triphosphate)
ATP is the energy currency of the cell. The gizmo shows how ATP molecules are generated during various stages and used for cellular activities.
3. NADH and FADH₂
These are electron carriers that transport energy-rich electrons to the electron transport chain. The gizmo displays their formation during earlier stages.
4. Oxygen
Oxygen acts as the final electron acceptor in the electron transport chain, essential for efficient energy production.
5. Mitochondria
Often called the powerhouse of the cell, mitochondria are depicted as the site where oxidative phosphorylation occurs.

Stages of Cellular Respiration Demonstrated by the Gizmo
Cellular respiration involves multiple interconnected stages. The cell energy cycle gizmo simplifies these complex pathways into visual, interactive steps.
1. Glycolysis
- Occurs in the cytoplasm
- Converts glucose into two molecules of pyruvate
- Produces a net gain of 2 ATP molecules
- Generates NADH, which carries electrons to later stages
2. Krebs Cycle (Citric Acid Cycle)
- Takes place in the mitochondrial matrix
- Processes pyruvate into carbon dioxide
- Produces high-energy electron carriers: NADH and FADH₂
- Generates a small amount of ATP directly
3. Electron Transport Chain (ETC) and Oxidative Phosphorylation
- Located in the inner mitochondrial membrane
- Uses electrons from NADH and FADH₂ to generate a proton gradient
- The flow of protons back into the mitochondrial matrix drives ATP synthesis
- Produces the majority of ATP during cellular respiration
