This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Proteins and Amino Acids, Subject name: Biochemistry
The protein synthesis is sorted out at / by 
Select and explain. 
A. Ribosomes, B. Mitochondria, C. Golgi - apparatus, D. Endoplasmic reticulum
C: Golgi - apparatus
Answer: C: Golgi - apparatus 
Explanation: (Golgi - Apparatus) (7 RS 7th)Golgi - complex (or Golgi - apparatus) or Dietysomes - Recent evidence suggests strongly that the complex serve as unique sorting device that recieve newly synthesized proteins* The post translational modifications takes place in the golgi lumen (median part) where the carbohydrate and lipid precursors are added to proteins to form glycoproteins and lipo proteins respectively* Ribosomes - are the centre of factories of protein synthesis* Rough Endoplasmic reticulum (RER) synthesizes membrane lipids and secretory proteins**
