what happen when glycogen concentration in the liver cells , when the con. of adrenalin in the blood stream increases ?

rn

name the commonly produced second messengers in hormone functioning ?

Increase in glycogen level of liver cells will result in lower level of insulin produced by pancreas so that more glucose is not converted into glycogen. 

Adrenalin is emergency hormones or hormones of fight or flight. Increase in its level in blood increases alertness, pupilary dilation, piloerection (raising of hair), increases heart beat, respiration rate and simulates the breakdown of glucose, lipids and proteins. 

cAMP i.e. cyclic AMP acts as secondary messenger in hormone functioning.
