Textbook Question
A cell with abundant peroxisomes would most likely be involved in:
a. Secretion
b. Storage of glycogen
c. ATP manufacture
d. Movement
e. Detoxification activities
Verified step by step guidance1
Understand the function of peroxisomes: Peroxisomes are organelles that play a key role in detoxification by breaking down harmful substances such as hydrogen peroxide and metabolizing fatty acids. They are also involved in lipid metabolism.
Analyze the options provided: Evaluate each choice based on the known functions of peroxisomes. For example, secretion (a) and movement (d) are not directly related to peroxisome activity.
Consider detoxification activities (e): Detoxification is a primary function of peroxisomes, as they contain enzymes like catalase that neutralize toxic substances.
Evaluate ATP manufacture (c): ATP production is primarily associated with mitochondria, not peroxisomes, so this option is unlikely to be correct.
Assess storage of glycogen (b): Glycogen storage is primarily a function of the liver and muscle cells, and it is not directly related to peroxisomes. Therefore, this option is also unlikely to apply.

1mKey Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Peroxisomes
Peroxisomes are small, membrane-bound organelles found in eukaryotic cells that contain enzymes for oxidative reactions. They play a crucial role in the metabolism of fatty acids and the detoxification of harmful substances, such as hydrogen peroxide, which is a byproduct of various metabolic processes.

Detoxification
Detoxification refers to the biochemical processes that remove or neutralize toxins from the body. In the context of peroxisomes, these organelles help convert toxic substances into less harmful compounds, making them essential for cellular health and function, particularly in liver cells.
Cellular Functions
Cells perform various functions, including secretion, storage, energy production, and detoxification. Understanding the specific roles of organelles like peroxisomes helps clarify which cellular activities are most relevant to their abundance, particularly in relation to detoxification and metabolic processes.
