1. Glycogen:
a.) Â Is mainly broken down to glucose-1-P byglycogen synthase
b.) Â Has branch chains that are attached at thebranch points by alpha 1,4
glycosidic linkages
c.) Â Built by glycogen phosphorylase when thereis high ATP and high glucose-6-
P
d.) Â Is an important storage form of glucose inour livers
e.) Â Both a and cÂ
2. What effect will high fructose-2,6-bisphosphate andlow ATP have on gluconeogenesis?
a.) Â It will shut gluconeogenesis down at thestep of triose phosphate isomerase
b.) Â It will speed gluconeogenesis up atfructose-1,6-bisphosphate phosphatase
c.) Â It will speed up gluconeogenesis byhyperactivating triose phosphate
isomerase
d.) Â It will speed up gluconeogenesis byhyperactivating phosphofructokinase
e.) Â Both b and d
