(a) Interpretation: The meaning of the given symbols involved in the first step of the citric acid cycle is to be stated. Concept Introduction: Anabolism and catabolism are the two pathways of metabolism . In anabolic pathway, large molecules are formed by the combination of small molecules. Anabolism is totally opposite to that of catabolism process. On the other hand, the catabolic pathway involves the breakdown of larger molecules into smaller molecules. In the Krebs cycle, acetyl-CoA helps to convert larger molecule of proteins, lipids and carbohydrates into smaller molecules. In each step of this cycle, a specific enzyme is involved.

There are eight chemical reactions that occur in the citric acid cycle process. The reactions of the citric acid cycle are shown in the figure below. You were introduced to several classes of organic reactions. These classes include esterification, decarboxylation, hydration reactions, dehydration of alcohols, oxidation of alcohols, oxidation of aldehydes, reduction of aldehydes, and reduction of ketones. Find at least one of these reaction classes in the citric acid cycle. List the reaction number and the reaction. Write a sentence or two on how you were able to make the classification.

The oxidation of 1 mol of glucose supplies enough meta-bolic energy to form 36 mol of ATP. Oxidation of 1 mol of a typ-ical dietary fat like tristearin (C₅₇H₁₁₆O₆) yields enough energyto form 458 mol of ATP. (a) How many molecules of ATP canform per gram of glucose? (b) Per gram of tristearin?
