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

B) combine the hydrogen with oxygen molecules to generate hydrogen peroxide

Explanation:

Peroxisome is an organelle found in almost all the eukaryotic cells. It is involved in detoxification and catabolism of various substances like alcohol, fatty acids and poisons. It does so by oxidizing the substance using molecular oxygen.

Peroxisome combines the molecular oxygen with hydrogen present in the substance so that it is removed from it in the form of hydrogen peroxide. Hydrogen peroxide is also toxic so it is further processed by the action of catalase enzyme.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
