Nitrate reductase

Homodimers, two identical subunits

Each subunit with 100kD

Each subunit contains 3 prosthetic groups:

FAD, heme, and molybdenum complexed to pterin (an organic molecule).

Some factor determine Ne

1.Sex ratio.

2.Variation between individual in reproduction success.

3.Fluctuation in population size.

4.The age structure of the population.

5.Mating is random.

Ne = Male + Female  (when both are equal)

Ne = 4 × n(male) × n(female)/n(male)+n(female) 

(When both unequal Ne is smaller than then sum of both)
