(a)
Interpretation: To identify the subunits that involve a B vitamin in the three-subunit block diagram for CoA.
Concept introduction: Coenzymes are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Coenzymes cannot perform on their own alone. CoA is also an example of the coenzyme.

Concept introduction: Coenzymes are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Coenzymes cannot perform on their own alone. CoA is also an example of the coenzyme.
Coenzyme A (CoA) is utilized in various metabolic reactions. The functions of coenzyme A include oxidation of pyruvate in the citric cycle and fatty acid oxidation. The main function of coenzyme A is to transfer the acetyl group in various metabolic pathways. The structure of coenzyme A is:

- Fatty acids and triglycerides are an important source of nutrition and a dense form of stored energy. Digestion of fats yields more energy per gram than digestion of carbohydrates. Each turn on the B-oxidation spiral results in the formation of a new acetyl COA molecule. This molecule can then be used to generate more energy in A) fatty acid synthesis B) ketolysis C) glycolysis D) tricarboxylic acid cycle E) oxidative phosphorylationarrow_forwardWhat metabolic intermediate is formed from the carbon skeleton of each amino acid? a. phenylalaninec. asparagine b. glutamic acidd. glycinearrow_forwardRigor mortis, the stiffening of muscles. after death is due to the depletion of intracellular ATP. Provide the biochemical basis of rigor mortisarrow_forward
- Which statements describe electron transport chain events? Two electrons pass between cytochromes through a series of redox reactions. Citrate metabolism results in the formation of one FADH2 and three NADH. NADH releases two hydrogen ions and donates two electrons to coenzyme Q. ATP synthase uses the energy from the redox reactions to generate ATP.arrow_forwardSupply the chemical equation (using the line structures) for the 3nd step of the b-oxidation of Stearate. Include the reactant(s), product(s), enzyme, coenzyme, etc Need answer step by steparrow_forwardGlucagon secretion increases (A) After a carbohydrate-rich meal (B) After a fat-rich meal (C) When blood glucose is high (D) When blood glucose is lowarrow_forward
