Question

Bacteria and archaea carry out the process of nitrogen fixation, which reduces atmospheric nitrogen, N2, to the biologically useful form NH3, also called ammonia. The nitrogenase complex consists of two proteins, reductase and nitrogenase, which catalyze the reactions of nitrogen fixation. Match each structural feature or function with the corresponding component of the nitrogenase complex.

a. also called the molybdenum—iron protein, or the MoFe protein
b. transfers electrons from a donor, such as frrredoxin, to the other component.
c. Homodimer
d. Heterotetramer

1. Reductase
2. Nitrogenase

Answer 1

a. Nitrogenase

b. Reductase

c. Reductase

d. Nitrogenase

Step-by-step explanation:

Reductase is a enzyme which promotes chemical reduction for a substance. It is also known as iron protein as iron is main component in reductase. Nitrogenase are molybdenum because they sulfur as co factor
