Which cells would be expected to contain the greatest number of ribosomes?
APancreatic cells making digestive enzymes
BFat cells storing triglyceride droplets
CSkin cells forming a protective sheet
DRed cells circulating in the vessels
Answer & Solution
Correct answer: A. Pancreatic cells making digestive enzymes
1. Ribosomes carry out protein synthesis, so their number tracks how much protein a cell makes.
2. Enzymes are proteins, and the pancreas creates several digestive enzymes.
3. The pancreatic cells that produce those enzymes contain many ribosomes.
4. Cells whose main job is storing fat or forming a barrier do not turn out protein at that rate.
5. Pancreatic enzyme-producing cells carry the greatest number.
6. Ribosome count therefore tracks protein output, which is another case of form following function.
