Quick acting hormones and Lag period hormones: Major differences
Quick
acting hormones
|
Slow
acting (Lag period) hormones
|
1.
They act immediately
after secretion (within a few seconds)
|
They act after a lag
period (may be hours or years)
|
2.
They are large sized
molecules so are not diffusible through cell membrane of target cells.
|
They are small sized
molecules so are diffusible through cell membrane
|
3.
The hormone
receptors are present on the cell membrane of target cells
|
The hormone
receptors are present in cytoplasm
|
4.
Their mode of action
is through cascade effect
|
Mode of action is
through mRNA synthesis.
|
5.
They will have
second messengers such as cyclic AMP (cAMP), IP3 etc.
|
No second messengers
|
6.
E.g. Proteinous,
peptide and amine hormones
|
E.g. Steroid
hormones
