Question

the pancreas is an organ present in some animals. it produces enzymes that are used in the digestive system of the animal. which cell structure is likely to be abundant inside pancreas cells? a. cell walls, because cell walls cannot be digested by enzymes b. chloroplasts, because chloroplasts provide the energy for making enzymes c. nuclei, because nuclei contain the instructions for synthesizing enzymes d. ribosomes, because enzymes are synthesized on ribosomes

Explanation:

Enzymes are proteins. Protein synthesis occurs on ribosomes. So, ribosomes are likely to be abundant in cells that produce enzymes. Cell walls are not relevant as they are not involved in enzyme - making in animals. Chloroplasts are for photosynthesis and not related to animal enzyme production. Nuclei contain DNA but the actual site of protein (enzyme) synthesis is the ribosome.

Answer:

D. Ribosomes, because enzymes are synthesized on ribosomes
