Answer 1

Answer:

it is a organelle present in the cell...

Answer 2

Answers:-

* ENDOPLASMIC RETICULUM *

DEFINITION:- THE ENDOPLASMIC RETICULUM IS THE LARGEST MEMBRANE - BOUND INTRA CELLULAR ORGANELLE FOUND IN EUKARYOTIC CELL(PROKARYOTES LACK MEMBRANE - BOUND. IT IS HIGHLY DYNAMIC ORGANELLE THAT RADIATES FROM THE NUCLEAR ENVELOPE TOWARDS THE PLASMA MEMBRANE

FUNCTION:-

=>PROTEIN SYNTHESIS:

•PROTEIN SYNTHESISATION IS ONE OF THE MAJOR FUNCTION OF ENDOPLASMIC RETICULUM

•THIS TRANSLOCATION ALSO CONTINUES IN THE RIBOSOMES LOCATED AT THE SURFACE OF ROUGH ENDOPLASMIC RETICULUM

=>LIPID SYNTHESIS:

•ER IS ALSO THE SITE OF LIPID BIOGENESIS. HERE, LIPID COMPONENTS ARE FIRST MOVED TO ENDOPLASMIC RETICULUM-GOLGI INTERMEDIATE COMPARTMENT WHERE THEY ARE BIOCHEMICALLY MODIFIED

•LIPID SYNTHESIS TAKES PLACE IN SMOOTH ENDOPLASMIC RETICULUM WHICH CONTAINS ENZYMES INVOLVED IN THE BIOSYNTHETIC PATHWAYS

=>CALCIUM STORAGE:

•ENDOPLASMIC RETICULUM IS OME OF THE MAIN STORAGE OF SITE FOR CALCIUM

•VARIOUS CHANNELS AND RECEPTORS ON THE ENDOPLASMIC RETICULUM ARE INVOLVED IN THE RELEASE OF THESE IONS INTO THE CYTOSOL WHERE THEY HELP REGULATE METABOLISM AMONG OTHER ACTIVITIES
