Answer:
In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.
Step-by-step explanation:
Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.
Examples of organelles and their functions are:
- Nucleus: contains DNA and in it occur the replication of this molecule and its transcription into RNA.
- Rough endoplasmic reticulum: protein synthesis and conjugation of these molecules occurs.
- Mitochondrion: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.
The organelles are then the structures that allow the development of the multiple functions that a cell has.
The other options are not correct because:
- Bacteria is a prokaryotic organism.
- Prokaryote refers to simple organisms that lack organelles.
- Proteins are biomolecules that allow the structure and function of living beings.
