Verified step by step guidance1
Identify the function described in the question: fatty acid oxidation and detoxification of hydrogen peroxide.
Recall that fatty acid oxidation is a metabolic process where fatty acids are broken down to produce energy, and detoxification of hydrogen peroxide involves breaking down this reactive oxygen species to prevent cellular damage.
Understand that peroxisomes are specialized organelles that contain enzymes for both fatty acid oxidation and the breakdown of hydrogen peroxide via catalase.
Recognize that liver cells have a high number of peroxisomes because the liver is a key site for metabolism and detoxification.
Conclude that the organelle abundant in liver cells and responsible for these functions is the peroxisome.
