endoplasmic reticulum

• What are the main components of the endoplasmic reticulum?

  The endoplasmic reticulum comprises smooth endoplasmic reticulum, rough endoplasmic reticulum, cisternal space, and cisternae

  
• What is the term for the interior space of the endoplasmic reticulum?

  Cisternal space

  
• What are the flattened sacs within the endoplasmic reticulum called?

  Cisternae

  
• How do the smooth and rough endoplasmic reticulum differ in structure and function?

  • Rough Endoplasmic Reticulum (RER):
  • Structure: Studded with ribosomes on the outer surface
  • Function: Protein synthesis and modification

  
  

  • Smooth Endoplasmic Reticulum (SER):
  • Structure: Lacks ribosomes on the outer surface
  • Function: Lipid synthesis and detoxification

  
• Which organelle is responsible for lipid synthesis and detoxification?

  Smooth endoplasmic reticulum

  
• What is the role of ribosomes in protein synthesis?

  • Ribosomes bind mRNA and tRNA to translate genetic information into polypeptide chains, forming proteins

  
• What is the rough endoplasmic reticulum (RER) primarily involved in?

  Protein synthesis for secretion
• What are the flattened membrane sacs in the RER called?

  Cisternae
• How is the rough endoplasmic reticulum connected to the nucleus?

  It is continuous with the nuclear envelope
• How does the rough endoplasmic reticulum work with ribosomes?

  Ribosomes synthesize proteins on the RER
• What is the primary function of the smooth endoplasmic reticulum (SER)?

  Lipid and steroid synthesis
• What is the structure of the smooth endoplasmic reticulum?

  Network of interconnected membrane tubules
• What does the smooth endoplasmic reticulum help with besides lipid synthesis?

  Detoxification and lipid storage
