Questions 13-20 refer to the following reaction scheme. Provide the requested information for each number pictured in the reaction scheme.  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.
