In Biology, carbon fixation is the reduction of inorganic carbon (carbon dioxide) to organic compounds by living organisms. The most prominent example is photosynthesis.
The citric acid cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidization of acetate derived from carbohydrates, fats and proteins into carbon dioxide.
So in terms of the reactants and products, citric acid cycle can be considered to be the reverse of carbon fixation.
What else can I help you with?
Does carbon fixation occur in the Calvin cycle?
Yes, carbon fixation occurs in the Calvin cycle.
Two carbon molecule that combines with a four carbon molecule already in the citric acid cycle to produce citric acid?
The two-carbon molecule that combines with a four-carbon molecule in the citric acid cycle to produce citric acid is acetyl-CoA. Acetyl-CoA condenses with oxaloacetate (a four-carbon molecule) to form citrate, the first step in the citric acid cycle.
What are the dark reactions of photosynthesis?
Carbon fixation (the Calvin Cycle).
Where does the Carbon go that is removed during the citric acid cycle?
it is removed in the form of CO2 out of the mitochondria and out of the cell
What are the Outputs of the citric acid cycle?
The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.
When does carbon fixation occur in plant biology?
During Calvin cycle
What is the most common method of carbon dioxide fixation?
The most common method of carbon dioxide fixation in nature is through the Calvin cycle, which occurs in the chloroplasts of plants during photosynthesis. In this process, carbon dioxide is converted into organic compounds that are essential for plant growth and development.
What fraction of the carbon dioxide exhaled by animals is generated by the reactions of the citric acid cycle if glucose is the sole energy source?
For every molecule of glucose oxidized in the citric acid cycle, 6 molecules of carbon dioxide are produced. Glucose is a 6-carbon molecule that is completely oxidized to carbon dioxide in this cycle. Therefore, the fraction of carbon dioxide exhaled by animals that is generated by the citric acid cycle is 100%.
The Calvin cycle happens during?
Carbon dioxide fixation in the light independent Calvin cycle occurs at night. Rubisco enzyme catalyzes the fixation of carbon dioxide to ribulose-1-5- bisphosphate.
What is the waste product form during the Krebs cycle?
A byproduct of the krebs cycle/citric acid cycle is carbon dioxide.
The Calvin cycle is a common method of what?
The Calvin cycle is a common method of photosynthesis, specifically the process by which plants, algae, and some bacteria convert carbon dioxide and energy from sunlight into glucose.
In cellular respiration a two carbon molecule combines with a four carbon with four carbon molecules to form citric acid as part of?
In cellular respiration, a two-carbon molecule (acetyl-CoA) combines with a four-carbon molecule (oxaloacetate) to form citric acid in the first step of the citric acid cycle (Krebs cycle). This process occurs in the mitochondria and is essential for the production of ATP through the oxidation of acetyl-CoA.
