The coenzyme that attaches to a 2-carbon acetate molecule during the preparatory reaction for the citric acid cycle is coenzyme A (CoA). This reaction forms acetyl-CoA, which serves as the key substrate for the citric acid cycle, linking glycolysis and the citric acid cycle. Acetyl-CoA is essential for the metabolism of carbohydrates, fats, and proteins.
A cofactor or coenzyme can attach to a protein to help catalyze a metabolic reaction by facilitating the reaction or acting as a carrier of chemical groups. These molecules can be inorganic ions, organic molecules, or other proteins that work together with the protein to enable the reaction to occur.
The preparatory reaction breaks down pyruvate (a 3-carbon molecule) into acetyl-CoA (a 2-carbon molecule) while producing carbon dioxide and reducing NAD+ to NADH. This reaction occurs in the mitochondrial matrix as a step before the citric acid cycle.
Oxygen gas is given off in the preparatory reaction of cellular respiration. It is the same as in photosynthesis in plants.
A coenzyme is a non-protein organic molecule that serves as a cofactor for an enzyme, helping it function properly. Coenzymes often participate in enzyme catalysis by carrying chemical groups between enzymes, and they can be recycled multiple times during enzymatic reactions.
Yes, without its coenzyme subunit, the apoenzyme will not be able to carry out its function. The coenzyme is essential for the proper functioning and activity of the enzyme. Without it, the apoenzyme will lack the necessary cofactor to catalyze the reaction efficiently or at all.
attaches to an enzyme and allows a chemical reaction to take place
The Preparatory Reaction, also known as the link reaction or pyruvate decarboxylation, occurs in the mitochondria after glycolysis. The primary inputs are pyruvate (produced from glycolysis), NAD⁺, and coenzyme A (CoA). The outputs of this reaction are acetyl-CoA, carbon dioxide (CO₂), and NADH. This reaction serves as a crucial link between glycolysis and the Krebs cycle, facilitating the conversion of glucose-derived pyruvate into a form that can enter the Krebs cycle.

Coenzymes assist enzymes in catalyzing biochemical reactions by transfering chemical groups or electrons from one molecule to another. They act as cofactors that are essential for enzyme activity, often participating in the reaction itself and helping the enzyme function properly.
The reaction that attaches fatty acid tails together is called esterification. Esterification involves a condensation reaction between a carboxylic acid group of one fatty acid and an alcohol group of another fatty acid to form an ester bond, resulting in the formation of a lipid molecule.

what coenzyme reduce without altering rate of reaction
Yes, glycolysis occurs before the preparatory reaction (pyruvate oxidation) and the citric acid cycle in the process of cellular respiration. Glycolysis breaks down glucose into pyruvate, which then enters the preparatory reaction to be converted into acetyl CoA and then further metabolized in the citric acid cycle.
