In order to attach a particular amino acid to the tRNA molecule that will transport it, an enzyme, an aminoacyl-tRNA  synthetase, is required, along with ATP. Initially, the enzyme has an active site for ATP and another for the amino acid, but it  is not able to attach the tRNA. What must occur in order for the final attachment to occur? Question options:  A) The ATP must first have to attach to the tRNA. B) The binding of the first two molecules must cause a 3-dimensional change that opens another active site  on the enzyme. C) The hydrolysis of the ATP must be needed to allow the amino acid to bind to the synthetase. D) The tRNA molecule must have to alter its shape in order to be able to fit into the active site with the other  two molecules. E)
