B) peroxisomes
C) rough endoplasmic reticulum
D) Golgi apparatus

Question

Quizplus · Accepted Answer

Peroxisomes are involved in the oxidation of fatty acids and ethanol. In this process, hydrogen peroxide (H2O2) is generated as a byproduct, which is then broken down by catalase enzymes also found in peroxisomes. Mitochondria are involved in aerobic respiration and the production of ATP, but they do not oxidize fatty acids or ethanol. Rough endoplasmic reticulum and Golgi apparatus are involved in protein synthesis and modification, respectively, and are not involved in the oxidation of fatty acids or ethanol.
