<span>The two basic molds are: Expendable
mold and permanent mold. </span>
Molding is a
process where a rigid frame (mold) is being used to manufacture by shaping liquid
or pliable raw materials. However, molding is synonymous to casting; casting is
a process where a liquid metal is delivered into a mold which contains a hollow
cavity of the intended shape.

Answer:
B. ensure the production of GTP in the case of succinyl-CoA
Explanation:
Succinyl CoA like acetyl-CoA has a thioester bond with very negative free energy of hydrolysis. In this reaction, hydrolysis of the thioester bond leads to the formation of phosphoester bond with inorganic phosphate. This phosphate is transferred to histidine residue of the enzyme and this high energy unstable phosphate is finall transferred to GDP resulting in generation of GTP.
Hence the answer is B. ensure the production of GTP in the case of succinyl-CoA.
