What is the relationship between photosynthesis and aerobic cellular respiration?
What is the relationship between photosynthesis and aerobic cellular respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration, oxygen is combined with hydrogen to form water.
In cellular respiration, what is oxidized and what is reduced?
In cellular respiration, what is oxidized and what is reduced?
The carbons in the glucose become oxidized, and the oxygens become reduced.
What is the role of electron carrier molecules in energy processing systems? Why are they necessary?
What is the role of electron carrier molecules in energy processing systems? Why are they necessary?
Electron carrier molecules carry electrons from one part of an energy processing system to another, providing the necessary energy and reducing power to make chemical reactions occur.

Study Notes
Relationship Between Photosynthesis and Cellular Respiration
- Photosynthesis produces glucose, which is essential for ATP production in cellular respiration.
- Carbon dioxide, a byproduct of cellular respiration, is utilized in photosynthesis.
- In photosynthesis, water is split to release oxygen; in contrast, oxygen combines with hydrogen in cellular respiration to form water.
Oxidation and Reduction in Cellular Respiration
- Cellular respiration converts one six-carbon glucose molecule and six oxygen molecules into six carbon dioxide and six water molecules.
- Carbon atoms in glucose undergo oxidation, losing electrons, while oxygen atoms are reduced, gaining electrons.
Role of Electron Carrier Molecules
- Electron carrier molecules transport electrons within energy processing systems, facilitating necessary chemical reactions.
- NADH serves as a crucial electron carrier, generated during glycolysis and the Krebs cycle, and utilized in the electron transport chain.
Use of Glucose in Cellular Respiration
- Glucose is not the only molecule that can undergo catabolism during cellular respiration; other substrates may also be used.
- Glucose is often used as a model due to its prominence in metabolism and energy production.
