(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.

- 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_forward
