4 hours after meal

when does dietary glucose kick in?

stored glucose is used at 16-18 hours during overnight fasting

when does glycogen kick in?

prolonged fasting and starts in about 4 hours after a meal, and gets more active over time

when does gluconeogenesis kick in?

liver

the immediately available glycogen is found where?

muscle

glycogen found in the ___ provides energy during bursts of activity during anaerobic conditions

acid maltase

-lysosomal alpha-1,4-glucosidase

glycogen degradation can also occur in lysosomes, what enzyme catalyzes this?

dephosphorylated

glycogen synthase is active when ____

phosphorylated

glycogen phosphorylase is active when ____

glucose-6-phosphatase

muscle cells do not have which enzyme so glucose can not be released to blood

glucagon
