Biology Question on Cell: the unit of life
Which of the following is responsible for the mechanical support, protein synthesis and enzyme transport?
A
Cell membrane
B
Mitochondria
C
Dictyosome
D
Endoplasmic reticulum
Answer
Endoplasmic reticulum
Explanation
Solution
Endoplasmic reticulum functions as cytoskeleton or intracellular and ultrastuctural skeletal framework by providing mechanical support to colloidal cytoplasmic matrix. Proteins and enzymes synthesised by ribosomes enter the channels of rough endoplasmic reticulum both for intracellular use as well as extracellular transport.
