Am I right because the book is showing a different answer?

Which of the following is/are typically larger in size in eukaryotes than in prokaryotes?

  1. cells
  2. amino acids
  3. ATP molecules
  4. Ribosomes

I believe the answer is 1 and 4 the book says 1,2, and 4 are correct.

Can someone please clarify if I or the book is correct?

Hey, is it a past IMAT question?

its an IMAT style question from an IMAT book

Then it’s a misleading quesiton, the book says 2 because they confused amino acids with proteins.

Beware as most IMAT books currently on the market contains so many errors and mistakes like that one

Yes proteins are bigger in size as compared to prokaryotes. Cell size and Ribosomes are large in eukaryotes. Prokaryotes are made up of 30s and 50s whereas eukaryotes are made of 60s and 40s subunits.

Prokaryotes don’t have membrane bound organelles while eukaryotic cells have true nucleus and membrane bound organelles thus the eukaryotic cells are more larger and complex than prokaryotic cells.

Eukaryotic proteins are typically more longer and complex than prokaryotic proteins.

Eukaryotes have 80S ribosomes while prokaryotes have 70S ribosomes.

The question becomes confusing on the option amino acids but since amino acids combine to make proteins therefore we can compare size of prokaryotic proteins vs eukaryotic proteins.
Hope it helps!
