Glycogen can be expanded quickly, by adding glucose residues to its many branches, and degraded quickly, by simultaneously removing glucose from the ends of these branches. The enzymes that catalyze these processes are specific for the ends of the glycogen polymer.

The correct answer is "nonreducing".

Explanation:

The enzymes that catalyze glycogen expansion are specific for the nonreducing ends. These enzymes are known as  glycosyltransferases, and Glycogenin is the most widely used. Glycogenin adds glucose specifically to the nonreducing ends of glycogen, and since glycogen have many nonreducing ends multiple residues of glucose are added in this process.

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

age range would be the answer
