The first step of the Calvin cycle is carbon fixation. RuBisCO (ribulose-1,5-bisphosphate carboxylase oxygenase) is the enzyme that fixates a carbon from carbon dioxide to RuBP (ribulose-1,5-bisiphosphate) to make 3-phosphoglycerate.

What two molecules combine to produce citric acid in the citric acid cycle?
Acetyl-CoA and oxaloacetate combine to produce citric acid (or citrate) in the citric acid cycle. This is the first step in the cycle, also known as the condensation step.
What escorts acetic acid produced from pyruvic acid into the first reaction of the citric acid cycle?
Coenzyme A (CoA) escorts acetic acid produced from pyruvic acid into the first reaction of the citric acid cycle by forming acetyl-CoA. Acetyl-CoA is then used as a substrate in the first step of the citric acid cycle to produce citrate.
Describe the steps of the Calvin Cycle?
1. 6 carbon dioxide molecules combine with six 5-carbon molecules forming twelve 3-carbon molecules. 2. The 12 3-carbon molecules are converted into high-energy forms. 3. 2 of the 12 3-carbon molecules are removed and the plant uses them to produce sugars, lipids, amino acids, and other compounds. 4. The 10 3-carbon molecules change back into six 5-carbon molecules, which combine with 6 more carbon dioxide molecules. The process starts over.
What is the first step in using amino acid as a fuel?
The first step in using amino acids as a fuel is to break them down through a process called catabolism. This process involves breaking the amino acids down into smaller molecules that can be converted into energy through pathways such as the citric acid cycle and oxidative phosphorylation.
