Final answer:
The oxidation of very long fatty acids in animal cells primarily takes place in the peroxisomes (Option E).
Step-by-step explanation:
The oxidation of very long fatty acids in animal cells occurs in the peroxisomes, which are organelles that specialize in breaking down fatty acids and detoxifying harmful substances. These organelles are responsible for carrying out oxidation reactions that break down fatty acids and amino acids, detoxifying harmful substances such as alcohol in the process.
Peroxisomes contain enzymes that safely break down the byproduct of these oxidation reactions, hydrogen peroxide (H₂O₂), into water and oxygen, thus preventing cellular damage.
Peroxisomes are small organelles enclosed by a single membrane and are responsible for carrying out oxidation reactions that break down fatty acids and amino acids. They also detoxify poisons that may enter the body. In the case of fatty acids, peroxisomes break them down into smaller molecules and convert them into energy.
Thus, the correct option is E.
