The Importance of Extensive Folding in Cellular Organelles

What is one benefit of folding in the ER related to protein processing?

• Reduces ribosome space

• Provides more space for ribosomes

• Eliminates protein synthesis

• Decreases cell's ability to process proteins.

What is the role of compartmentalization in mitochondria?

• Create distinct regions for concentration gradient

• Eliminate ATP synthesis

• Reduce energy production

• Decrease surface area

Which organelle's folding is crucial for ATP synthesis?

• Golgi apparatus

• Mitochondria

• Smooth ER

• Rough ER

What is the common structural feature of mitochondria and chloroplasts?

• Single membrane

• Double membranes
