Human pancreatic cells synthesise digestive enzymes in large quantity due to the presence of a large number of
Correct answer: C. Golgi bodies
- A. Ribosomes
- B. Lysosomes
- C. Golgi bodies
- D. Smooth endoplasmic reticulum (SER)
Explanation
The correct answer is Golgi bodies. Pancreatic cells synthesize large quantities of digestive enzymes, which need to be processed and packaged for secretion. The Golgi bodies (or Golgi apparatus) are responsible for modifying, sorting, and packaging proteins for secretion. Ribosomes synthesize proteins, but they do not handle the secretion process. Lysosomes are involved in breaking down waste materials within the cell, not in enzyme secretion. The smooth endoplasmic reticulum is involved in lipid metabolism and detoxification, not in protein processing. Therefore, for cells that produce and secrete large amounts of enzymes, the Golgi bodies play a crucial role.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.

Most scientists subscribe to the theory of endosymbiosis to explain the presence of mitochondria in eukaryotic cells. According to the theory of endosymbiosis, early pre-eukaryotic cells phagocytosed free living prokaryotes, but failed to digest them. As a result, these prokaryotes remained in residence in the pre-eukaryotes, and continued to generate energy. The host cells were able to use this energy to gain a selective advantage over their competitors, and eventually the energy-producing prokaryotes became mitochondria. In many ways, mitochondria are different from other cellular organelles, and these differences puzzled scientists for many years. The theory of endosymbiosis concisely explains a number of these observations about mitochondria. Perhaps most of all, the theory explains why aerobic metabolism is entirely limited to this one organelle, while other kinds of metabolism are more distributed in the cellular cytosol.Many organisms have evolved the use of an uncoupling protein, UCP1. UCP1 is able to generate heat for animals that must live in the cold, and exerts its effect in the mitochondria. UCP1 functions similarly to ATP synthase, in that it allows protons out of the intermembrane space and into the mitochondrial matrix, but generates energy in the form of heat instead of ATP. Where are we most likely to find UCP1?
