Answer:
e. Researchers suspect that portions of the reverse cycle may have been responsible for fixing CO2
Explanation:
Carbon fixation refers to the metabolic process by which inorganic carbon, especially carbon dioxide (CO2), is converted to organic matter. Moreover, the citric acid cycle (TCA) is a metabolic pathway capable of generating energy by the oxidation of acetate (which is derived from carbohydrates, fats, and proteins) into CO2. The reverse TCA cycle is a form of carbon fixation that uses CO2 and water molecules to produce organic carbon molecules. The enzymes that are unique to the reverse TCA cycle include ATP citrate lyase (required to cleave citrate into acetyl CoA and oxalacetate); 2-oxoglutarate:ferredoxin oxidoreductase (OGOR); and pyruvate ferredoxin oxidoreductase (required for pyruvate decarboxylation/oxidation).
