The path of a labeled carbon atom through the biological processes of photosynthesis and respiration
THE END
Cellular Perspiration
- In the glycolysis stage glucose (a 6-carbon compound) is broken into two 3-carbon pryuvate molecules.
- Then the pryuvate loses a carbon dioxide molecule which bonds to a coenzyme A and forms acetyl-CoA
- In the Krebs cycle, each acetyl-CoA goes through a series of reactions with other organic compounds that breaks it down and releases carbon dioxide.
Glucose
Transformation between Photosynthesis and Respiration
- The carbon atom is able to take a transition between photosynthesis and respiration. This happens because carbon dioxide is the reactant of one process and the product of the other.
- Algae, Plants and some bacteria take in carbon dioxide from the atmosphere to be used for photosynthesis and release oxygen. Organism use this released oxygen for respiration, which releases carbon dioxide.
Releases carbon dioxide through respiration trees take in through photosynthesis.
Photosynthesis
Light-Independent Reactions
- Carbon dioxide molecules from the atmosphere go in the Calvin Cycle. This process takes place in the stroma.
- Adenine triphosphate and Nicotinamide adenine dinucleotide phosphate change carbon dioxide to create stable long term energy. For example, glucose and carbohydrates are stable long term energy.
CO2= Carbon Atom
Photosynthesis occurs within two stages:
- Light-dependent reactions
- Light-independent reactions
Light Indepenent Reactions continuation.
- In the stroma, the carbon dioxide molecules mix with other carbon-based molecules already in the organelle to form three carbon compounds.
- Six carbon dioxide molecules already in the organelles are used to make one six-carbon glucose molecule.
During these stages water, carbon dioxide gas, and oxygen gas are changed into carbohydrates. They have help from the suns light, which is the energy source.

- In order, for the electrons and energy to be transferred to the next phase in the light-independent reactions. Adenine triphosphate and Nicotinamide adenine dinucleotide phosphate, is formed.
Carbon Dioxide
- Photosynthesis occurs in the thylakoids, where the chloroplast absorbs energy. This energy comes from the sun, and gives off high amounts.
