Q: Which cytologist explained the role of the Endoplasmic Reticulum (ER) in protein processing and sorting in various types of cells in the 1960s?
  • A. Ralph M. Steinman
  • B. George E. Palade
  • C. Cyril Darlington
  • D. Nettie Stevens
Correct Answer: Option B - George Emil Palade was a Romanian-American cell biologist who made significant contribution to the understanding of the cell structure and function. In the 1960s, George E. Palade used electron microscopy to study the structure and function of the ER in pancreatic cells. His work revealed how proteins synthesized in the ER are processed and sorted for transport to their final destinations, such as the Golgi apparatus or the cell membrane. He was awarded the Nobel Prize in Physiology or Medicine in 1974.
