Glycogenesis and glycogenolysis

The key regulatory enzyme of the process of glycogenolysis is

• Glycogen synthase

• Glycogen phosphorylase

• Glycogen debranching enzyme

• Glycogen branching enzyme

glycogenesis happens due to the following except

• in excess of glucose

• release of glucagon

• release of insulin

• after digestion

what acts faster when glucose is needed

• gluconeogenesis

• glycogenesis

• glycogenolysis

• glycolysis

primary storage site for glycogen is

• liver and heart

• liver and brain

• liver and skeletal muscle

• brain and heart

in which cellular compartment glycogenesis occur

• matrix of mitochondria

• cytoplasm

• inter membrane space of mitochondria

• cytosol

glycogenesis is initiated by

• glucose

• glycogenin

• glucose 6 phosphate

• UDP glucose

The hormones glucagon and ---------------- stimulate glycogenolysis

• insulin

• adrenalin

• octapamine

• dopamine

How does glycogenolysis break down glycogen into glucose

• it cuts the glycogen in half

• it starts at the end of the branches and breaks glucose off one at a time

• it brings the entire glycogen molecule to be broken into energy

• it re arranges the glycogen molecule into glucose

In which type of cell does glycogenolysis occur

• myocytes

• hepatocytes

• both

• neither

Name the bond making up branches in glycogen

• alpha 1,4 glycosidic bond

• phospho diester bond

• alpha 1,6 glycosidic bonds

• conalent bond
