Women have a smaller quantity of the enzyme which breaks down alcohol.

Alcohol dehydrogenase (ADH)

Alcohol dehydrogenase (ADH) enzymes are found in many organisms. These enzymes break down alcohol in the stomach and they also take part in the production of aldehyde and alcohol groups during the formation of various metabolites. Women have a lesser quantity of the alcohol dehydrogenase enzyme than men and therefore, women’s blood level is higher than that of men when they take a little alcohol.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
