RIBOSOMES

• What is the primary function of ribosomes?

  Protein synthesis
• What are the two subunits of ribosomes composed of?

  Special proteins and ribosomal RNA (rRNA)
• What must happen before protein synthesis can begin in ribosomes?

  The two subunits must join together
• Where are free ribosomes located?

  Throughout the cytoplasm
• What happens to proteins manufactured by free ribosomes?

  They enter the cytosol
• What are the key components and functions of ribosomes?

  • Function: Protein synthesis
  • Components:
  • Two subunits (1 large, 1 small)
  • Special proteins
  • Ribosomal RNA (rRNA)
  • Location: Free ribosomes throughout cytoplasm
  • Process: Subunits join before synthesis; proteins enter cytosol
