The cytochemical marker ‘Acid Phosphatase’ acts on which of the following regions?
Cis-region of Golgi complex
Median region of Golgi complex
Trans region of Golgi complex
GERL region
Option 4 is correct because the cytochemical marker acid phosphatase acts on the Golgi-associated endoplasmic reticulum lysosome (GERL). Acid phosphatase activities exist in GERL region and in side-cisternae which are mature and also in vacuoles which are condensing.GERL was examined with cytochemical markers, two enzyme markers (TPPase) and (ACPase) and osmium impregnation in the ameloblasts.
Explanation for the correct options :
Option 1 is incorrect because the cytochemical marker acid phosphatase does not act on the cis-region of the Golgi complex.
Option 2 is incorrect because the acid phosphatase which is a cytochemical marker does not act on the median region of the Golgi complex.
Option 3 is incorrect because acid phosphatase does not show its activity in the trans region of the Golgi complex.
