How can an obligate aerobe still grow without oxygen by carrying out anaerobic respiration?

this lab is about nitrate reduction and how it is one form of anaerobic respiration.

Solutions

Expert Solution

solution

Obligate aerobes are live in the presence of oxygen only but some bacterial strain can utilize NO3 instead of O2 as an electron acceptor to proceed anaerobic respiration.
Enzyme Nitrate reductase (on inner membrane) is responsible for nitrate reduction in obligate aerobe to start anaerobic respiration.
Nitrate is a molecule having high reduction potential act as terminal electron acceptor in many anaerobic bacteria.

You are studying a bacterial strain that is an obligate aerobe. The bacteria can do some fermentation and produce lactic acid as an end product, but normally only when starved for oxygen and can’t survive on fermentation alone. Your rival dumps a chemical into your prize culture. This chemical binds to the first protein in the electron transport chain, locking it into a fully reduced and inhibited state permanently. Describe the predicted consequences of this poison on the function of...

Yeast make alcohol in the absence of oxygen by a process called fermentation (i.e., anaerobic respiration). Complete fermentation of one of the sugar glucose (C6 H12 O6) will generate two moles of ethanol (C2 H6 O), two moles of carbon dioxide (CO2) gas, and tow moles of the important molecule ATP (C10 H16 N5 O13 P3), using in cellular transfers. You perform an experiment to make alcohol, so you set up an anaerobic fermentation system using yeast. You add 135...

Bacteria can perform aerobic and anaerobic respiration depending on their enzymes and metabolic needs. A student argued that aerobic and anaerobic respiration should produce the same amount of ATP. He reasoned that they both use basically the same process; only the terminal electron acceptor is different. What is the primary error in this student’s argument? Think about the different organisms in the body and in nature. Discuss how some produce their energy by anaerobic and aerobic metabolism. Discuss what would...
