Front

What is the primary function of ribosomes?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between rough and smooth endoplasmic reticulum?

Back

Rough ER has ribosomes on its surface and is involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid synthesis.
