Respiration using nitrate as the electron acceptor involves secretion of organic molecules as waste because external electron acceptors are not present
A. True
B. False
Homework Answers
False.
In anaerobic respiration nitrate is use as a terminal electron
acceptor, or dissimilatory denitrification, which is the main route
by which fixed nitrogen is returned to the atmosphere as molecular
nitrogen gas.

Some bacteria can use nitrate as an electron acceptor instead of oxygen, reducing it to nitrite. This requires an enzyme called nitrate reductase. The reduction and oxidation redox equations I am using are: NO3- +2H+ +2e- ---> NO2- + H2O NAD+ + 2H+ +2e- ---> NADH + H+ I calculated the Gibbs free energy change under standard state conditions for the oxidation of NADH by nitrate to be -144.75 kJ/mol. Please use the value to help solve part a. Please...
