Question

A cell X in a glandular tissue makes and secretes proteins. Another cell Y in that tissue synthesizes and secretes steroids. If you were to compare the two cells, what differences would you expect to see?

• The two cells would look identical

• Cell X would have more smooth endoplasmic reticulum than cell Y

• Cell X would have more rough endoplasmic reticulum than cell Y

• Cell X would have less rough endoplasmic reticulum than cell Y

Answer 1

Answer

Option C) Cell X would have more rough endoplasmic reticulum than cell Y

• Endoplasmic reticulum is a tube like organelle that functions to produce protein and lipids.
• Rough endoplasmic reticulum consist ribosomes attached on its surface that give rough appearance to this organelle.
• Ribosomes are primary site for protein synthesis.
• Smooth endoplasmic reticulum synthesize lipids.
• As cell X in a glandular tissue makes protein, it has more rough endoplasmic reticulum than cell Y.
