Match the enzymes in glycogen metabolism with the correct function.
1) Glycogen Phosphorylase - Breaks down glycogen into glucose
2) Glycogen Synthase - Synthesizes glycogen from glucose
3) Debranching Enzyme - Catalyzes the transfer of glucose units from one chain of glycogen to another
4) Phosphoglucomutase - Converts glucose-6-phosphate to glucose-1-phosphate
