Questiоns 17–24 refer tо the fоllowing reаction scheme. Provide the requested informаtion for eаch number pictured in the reaction scheme. Select ONE best answer for each. (24 pts total) Image Description The reaction proceeds in the following manner: In reaction 1, 2-amino-3-methylbutanoate is converted to 3-methyl-2-oxobutanoic acid in the presence via the replacement of an amine group with a ketone. In reaction 2, 3-methyl-2-oxobutanoic acid is converted to isobutyryl-CoA via the replacement of a carboxylic acid with SCoA. In reaction 3, isobutyryl-CoA is converted to crotonyl-CoA (in which one of the terminal CH3 groups is converted into a CH2 group as a C=C double-bond is formed).In the next reaction, which is not numbered in the diagram, crotonyl-CoA is converted to 3-hydroxy-2-methylpropionyl-CoA via attachment of an alcohol to the terminal CH2 with a double C=C bond, converting the C=C bond back into a C-C single bond. And then, to 3-hydroxy-2-methylpropionate via replacement of SCoA with an oxygen. In the next reaction, involving molecule 4 in the diagram, 3-hydroxy-2-methylpropionate is converted into 3-formyl-2-methylpropionate in the presence of molecule 4 via converting the terminal oxygen into an aldehyde. Molecule 4 is converted into an unknown in the process. In the next reaction, involving molecule 5 in the diagram, 3-formyl-2-methylpropionate is converted into propionyl-CoA (whose structure is not shown) in the presence of an unknown cofactor or substrate, which is converted into molecule 5. Additionally, NAD+ is utilized and converted into an unknown product in the process. In the next reaction, involving molecule 6 in the diagram, propionyl-CoA is converted into D-methyl malonyl CoA in the presence of molecule 6. In the next reaction, creating molecule 7 in the diagram, D-methyl malonyl CoA is converted to the unknown product 7. In the final reaction, creating product 8 in the diagram, Product 7, in the presence of cobalamin, is converted to the unknown product 8.
