**Understanding Beta-Oxidation of Fatty Acids****Question 17:**The shown reaction is one of the four repeating steps during fatty acid β-oxidation. Which of the following statements is correct for the shown reaction?``` A B | |HO—CH2—C—H—C—C=O CH2—C=O | || -> | || H O | HO—H CH2—C—S—CoA | | HO—C—C=O CO—S—CoA || | || | O HO O HO | | | | HO CoA HO—C—S—CoA O | | HO—H```**Answer Choices:**A. The small molecule in box A is FADB. It is the second oxidation reaction during β-oxidationC. Both A and BD. Neither A nor B**Diagram Illustration:**In the provided chemical reaction, two molecules are indicated by the labels 'A' and 'B':- The molecule in box 'A' is involved in the oxidation process, which facilitates the conversion of the initial molecule to the final product.- The molecule in box 'B' represents the product of this reaction.**Explanation:**In the context of fatty acid β-oxidation, the process typically involves four repeating steps:1. Dehydrogenation, catalyzed by acyl-CoA dehydrogenase, producing FADH2.2. Hydration, catalyzed by enoyl-CoA hydratase.3. Dehydrogenation, this time catalyzed by β-hydroxyacyl-CoA dehydrogenase, producing NADH.4. Thiolysis, catalyzed by thiolase, generating one acetyl-CoA and a shortened acyl-CoA.In this reaction:- **Box A** likely contains NAD+ (not FAD) as the coenzyme that is reduced to NADH, signifying the second dehydrogenation step in β-oxidation.- **Box B** represents the product oxidized from the original molecule, indicating the conversion relation between the reactants and products.**Conclusion:**Based on the understanding of the β

Can you please pick the right answer in each parentheses? The pentose phosphate pathway provides a number of critical functions including ["production of ribose-5-phosphate", "production of NADH"] that is vital for ["synthesis of nucleotides and coenzymes", "oxidative phosphorylation"] . This pathway is divided into oxidative and non-oxidative steps. The latter steps ["are involved in the conversion of various sugar phopshates, so called ["carbon shuffle reactions"", "are directly involved in NADPH production"] . If ["NADP+", "NAD+"] levels are high, flux through the pentose phosphate pathway is promoted by allosteric regulation of glucose-6-phosphate dehydrogenase. If reducing equivalents derived form the pentose phosphate pathway are high, glucose-6-phosphate is directed toward ["a phosphatase and then export from the cell", "glycolysis"] .
