What is the coenzyme that attaches to a 2-carbon acetate molecule during the preparatory reaction for the citric acid cycle?
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.

What attaches a protein to catalyze a metabolic reaction?
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.
What does the prepartory reaction break?
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.
What does the preparatory reaction produce?
Oxygen gas is given off in the preparatory reaction of cellular respiration. It is the same as in photosynthesis in plants.
What is a characteristic of a coenzyme?
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.
Will an apoenzyme that looses its coenzyme subunit will be non-functional?
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.
What is the basic function of a coenzyme?
attaches to an enzyme and allows a chemical reaction to take place
What attaches a protein to catalyze a metabolic reaction?

The basic function of a coenzyme?
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.
What is the reaction called that attaches fatty acids tails together?
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 does the preparatory reaction produce?
Oxygen gas is given off in the preparatory reaction of cellular respiration. It is the same as in photosynthesis in plants.

What is a characteristic of a coenzyme?

What is a coenzyme and what is its function?
temporary carriers of atoms being removed from or added to a substrate during a reaction.
Does glycolysis occur before the preparatory reaction and the citric acid cycle?
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.
Will an apoenzyme that looses its coenzyme subunit will be non-functional?
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.
What is acethyl CoA?
What is Coenzyme A?Photosynthetic plants convert light energy into chemical energy. Using their photosynthetic products (ATP, NAD(P)H, and carbon skeleton), plants have unique ability to assimilate soil and atmospheric elements into compounds usable by human and animals. Photosynthesis provides carbon precursors and cofactors for many of the essential plant biosynthetic pathways, of which coenzyme A (CoA) is one of their products.Function of Coenzyme A in PlantsCoenzyme A is a cofactor for 4% of the enzymes in plants. Coenzyme-a is converted into acyl-coenzyme-A (CoA), mainly acetyl-coenzyme-A (CoA), upon reaction with carbohydrate catabolites. Acetyl-coenzyme-A (CoA) is a key substrate in important metabolisms such as citric acid cycle (TCA cycle), fatty acid, some amino acids, flavonoid, wax, isoprenoid, lignin synthesis and storage lipid degradation. These biochemical pathways generate intermediate metabolites that play a role in the adaptation of the plant to changing environmental conditions, defense against pests, nutritional value, pigment and structural component synthesis. Acetyl-coenzyme-a (CoA) also mediates synthesis of secondary metabolites (natural products) of pharmaceutical and industrial significance.
