Peroxisomes and Their Functions

The video explains the role of peroxisomes in cells, comparing them to superheroes that clean up toxins. Peroxisomes are spherical organelles with a phospholipid bilayer and crystalloid core, found in eukaryotic cells. They break down fatty acids and protect cells from reactive oxygen species, which can be harmful. Additionally, peroxisomes assist the liver and kidneys by eliminating hydrogen peroxide. The video concludes with a reminder about the importance of kindness.

What is the primary role of peroxisomes in the cell?

• To synthesize proteins

• To store genetic information

• To produce energy

• To break down toxins and unwanted chemicals

What is the main structural component of peroxisomes?

• A single lipid layer

• A phospholipid bilayer and a crystalloid core

• A protein shell

• A carbohydrate matrix

How do peroxisomes differ from lysosomes?

• Peroxisomes synthesize proteins, while lysosomes synthesize lipids

• Peroxisomes break down proteins, while lysosomes break down fatty acids

• Peroxisomes break down fatty acids, while lysosomes break down proteins

• Peroxisomes store energy, while lysosomes store waste

What harmful molecules do peroxisomes protect the cell from?

• Lipids

• Reactive oxygen species

• Carbohydrates

• Proteins

Which of the following is a byproduct of normal cellular respiration that peroxisomes help manage?
