Question

The RER in the cell synthesised a protein which would be later used in building the plasma membrane. But it is observed that the protein in the membrane is slightly different from the protein made in the RER. The protein was probably modified in another cell organelle in the given diagram.

• A. D
• B. A
• C. B
• D. C

Answer 1

Answer: (A)

D

Option A is correct as “D” in the figure is showing Golgi body which comprises flattened sacs stacked on each other. It serves to processes secretory and synthetic products from the ER and then transports the finished products into cell parts or secretes them to the outside of the cell.

Option B is incorrect as “A” in the figure is showing mitochondria are double membrane-bound eukaryotic cell organelles and serve as the site for cellular respiration, produce an enormous amount of energy, and therefore also known as the powerhouse of the cell.

Option C is incorrect as “B” in the figure is referring to the nucleus present in the cell.

Option D is incorrect as "C" in the figure is referring to the endoplasmic reticulum an eukaryotic cellular organelle with a network of tubules, vesicles, and cisternae. It serves in the synthesis and transport of proteins and lipids.
