Ribosomes: Justify presence of both attached & free ribosome in cytoplasm.

 Ribosomes: Justify presence of both attached & free ribosome in cytoplasm. 


Ribosomes exist in two forms in the cytoplasm: free ribosomes and attached (bound) ribosomes, each serving distinct functions:

  1. Free Ribosomes: Float freely in the cytoplasm.

Function: Synthesize proteins that function within the cytoplasm (e.g., enzymes for metabolism).

Attached Ribosomes:

  • Bound to the rough endoplasmic reticulum (RER).


Function: Protein Synthesis – Produces proteins for secretion, plasma membrane, and organelles (e.g., lysosomes).

Transport – Sends proteins to the Golgi apparatus for further processing and distribution.
