Cellular Respiration Flashcards
What are the three stages of cellular respiration?
Glycolysis, Citric Acid Cycle (Krebs cycle), and Electron Transport Chain.
Where does glycolysis occur?
In the cytoplasm of the cell.
Where do the Citric Acid Cycle and Electron Transport Chain occur?
In the mitochondria.
What is the role of oxygen in the electron transport chain?
Oxygen is the final electron acceptor, combining with electrons and protons to form water (H₂O).
How many ATP molecules are produced in total from one glucose molecule during cellular respiration?
Up to 38 ATP molecules. 2 ATP from Glycolysis, 2 from the Krebs Cycle, and 34 from NADH and FAD2 in the ETC (approximately).
How is energy released in respiration and what processes happens when the energy is released? And what is that process called.
The energy is slowly released through a bunch of steps where glucose is broken down. Each step releases a tiny bit of energy as electrons and hydrogens are striped from glucose. This process is called oxidation.
How is ATP made during Aerobic Respiration? And what is additional made during this process?
Glucose from our food and oxygen from the air we breathe is used to make ATP. This also additionally makes carbon dioxide that we breathe out and water (H2O) as waste products.
What does the oxidation of glucose do and what is it needed for?
The oxidation of glucose releases energy which is need and is used to make ATP. This happens gradually.
What are the 4 stages of Aerobic Respiration?
- Glycolysis
- The link Reaction
- The Krebs Cycle
- The Electron Transport Chain
Where does Glycolysis occur in a cell?
The cytoplasm
