Final answer:
Peroxisomes are the organelles that degrade long chain fatty acids and detoxify foreign molecules by carrying out oxidation reactions. They contain enzymes like catalase to safely breakdown hydrogen peroxide into water and oxygen, therefore preventing cellular damage.
Step-by-step explanation:
The organelles that degrade long chain fatty acids and toxic foreign molecules are peroxisomes. These versatile organelles carry out oxidation reactions to break down fatty acids and amino acids, and they are essential for the detoxification of poisons, including alcohol in liver cells. Peroxisomes safely contain and break down hydrogen peroxide, a byproduct of these oxidation reactions, into water and oxygen, preventing potential damage to the cell.
In contrast,lysosomes use enzymes to break down foreign matter and dead cells, but are not primarily responsible for the breakdown of fatty acids and detoxification. Therefore, the correct answer to the question is a) Peroxisomes.
