In a liver cell detoxifying alcohol and some other poisons, the enzymes of the peroxisome remove hydrogen from these molecules and ________.
A) combine the hydrogen with water molecules to generate hydrogen peroxide
B) combine the hydrogen with oxygen molecules to generate hydrogen peroxide
C) combine the hydrogen with hydrogen peroxide to generate oxygen
D) combine the hydrogen with hydrogen peroxide to generate oxygen and water

Question

Quizplus · Accepted Answer

The enzymes in peroxisomes remove hydrogen from toxic molecules and combine it with oxygen to generate hydrogen peroxide (H2O2), which is then further broken down into harmless substances by other enzymes within the peroxisome. Choice A is incorrect because hydrogen peroxide is not formed by combining hydrogen and water molecules. Choice C and D are incorrect because oxygen or water is not generated by combining hydrogen with hydrogen peroxide.
