Question

question 7
how do peroxisomes neutralize poisons such as alcohol?
by producing hydrogen peroxide
by converting alcohol into glucose
by producing atp
by breaking down proteins

Explanation:

Peroxisomes contain enzymes that can oxidize substances like alcohol. One of the by - products of these oxidation reactions is hydrogen peroxide ($\ce{H2O2}$). Although hydrogen peroxide is toxic in high amounts, peroxisomes also contain catalase, which can break down hydrogen peroxide into water and oxygen. The initial production of hydrogen peroxide is part of the process of neutralizing poisons such as alcohol.

• Converting alcohol into glucose is not a function of peroxisomes. Gluconeogenesis (the production of glucose from non - carbohydrate sources) occurs mainly in the liver and kidneys through a series of metabolic pathways that are different from peroxisomal functions.
• Producing ATP is a function of mitochondria (through oxidative phosphorylation) and glycolysis (in the cytoplasm). Peroxisomes are not the main organelles for ATP production.
• Breaking down proteins is a function of lysosomes (through proteolytic enzymes) and the ubiquitin - proteasome system in the cytoplasm, not peroxisomes.

Answer:

By producing hydrogen peroxide
