Question 4
Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in  separate compartments called organelles.

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:

- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.

- <u>Mitochondrion</u>: 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:

  • <em><u>Bacteria</u></em><em> is a prokaryotic organism. </em>
  • <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles. </em>
  • <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
