Which of the following cellular processes are possible in eukaryotes, but not in prokaryotes?Oxidative phosphorylationDNA replicationGlycolysisPhagocytosis

To differentiate between cellular processes that occur in eukaryotes but not in prokaryotes, we need to understand how these organisms are structured and where certain processes take place.

1. Oxidative Phosphorylation: This process occurs in the mitochondria of eukaryotic cells. Prokaryotes lack mitochondria; instead, they perform similar energy-generating processes in their cytoplasmic membrane. Thus, oxidative phosphorylation is generally considered to occur in eukaryotes.

2. DNA Replication: Both eukaryotes and prokaryotes can replicate DNA. Eukaryotic DNA replication is complex and involves multiple origins of replication, while prokaryotic DNA is circular and has a single origin. Therefore, DNA replication occurs in both cell types.

3. Glycolysis: This is the initial metabolic pathway that breaks down glucose in both prokaryotes and eukaryotes. Glycolysis occurs in the cytoplasm of both types of cells.

4. Phagocytosis: This is a process by which cells engulf large particles or other cells. Phagocytosis is a characteristic feature of many eukaryotic cells (like immune cells); prokaryotes do not have the cellular machinery required for this process because they lack a defined nucleus and other organelles.

Conclusion

Based on the analysis: The processes possible in eukaryotes, but not in prokaryotes, are Oxidative phosphorylation and Phagocytosis.
