Question

Which side of Golgi apparatus has thin membranes?

• A. Concave distal side
• B. Concave proximal side
• C. Convex distal side
• D. Convex proximal side

Answer 1

The correct option is D Convex proximal side

• Golgi apparatus is a cellular organelle which consists of folded and flattened membranes (cisternae) within the cytoplasm.
• It is mainly responsible for secretion and intracellular transport.
• There two faces of the cisternae-
  

1. Cis face (convex face or forming face)- it faces the endoplasmic reticulum and receives vesicles from ER which contain enzymes or proteins and have thin membranes.
   
2. Trans face (concave face or maturing face)- it faces away from the endoplasmic reticulum and releases golgian vacuoles which contain modified enzymes or proteins.

• So, the correct answer is 'Convex proximal side'.
