When glycogen is broken down to be used as an energy source, glucose units are removed one at a time from the nonreducing ends by enzymes. Web20 mrt. 2024 · Explanation: In glycogen, about 10% of the glucose units are branched (Lehninger. p304-305). The molecule has one reducing end (right hand end of chain) but many non-reducing ends (left hand ends) due to the branches. The non-reducing ends are the locations of all glucose additions or removals.
