Expert Solution

1) anaerobic respiration is the process by which glucose is oxidized completely to carbon dioxide with the production of ATP, in the absence of oxygen.

pyruvate is formed by the glycolysis of the glucose, pyruvate is further oxidized to carbon dioxide via aerobic respiration,

in aerobic respiration the final electron acceptor is oxygen it is reduced to water.

In anaerobic respiration NO3-, Fe3+, SO42-, etc can be used as final electron acceptors. so the answer is a) Fe3+.

2) In anaerobic respiration, glucose is oxidized to 6 molecules of carbon dioxide

NAD+ accepts high energy electrons from glucose during oxidation reactions and gets reduced to NADH, ATP is formed by both substrate-level phosphorylation and via electron transport chain and ATP synthase ( ATP synthase uses the energy of H+ gradient generated by electron transport chain to produce ATP from ADP and Pi)

so the answer is a) carbon dioxide.

3) anaerobic respiration is the process by which glucose is oxidized completely to carbon dioxide with the production of ATP, in the absence of oxygen.

pyruvate is formed by the glycolysis of the glucose, pyruvate is further oxidized to carbon dioxide via aerobic respiration,

in aerobic respiration the final electron acceptor is oxygen it is reduced to water.

In anaerobic respiration NO3-, Fe3+, SO42-, etc can be used as final electron acceptors. so the answer is a) NO3-.

When O2 is added to an anaerobic suspension of cells consuming glucose at a high rate,...

When O2 is added to an anaerobic suspension of cells consuming glucose at a high rate, the rate of glucose consumption drops significantly as the O2 is consumed; the accumulation of lactate also ceases. First observed by Louis Pasteur in the 1860s, this effect is characteristic of most cells capable of aerobic and anaerobic metabolism. a) Why does lactate cease to accumulate upon addition of O2? b) Why does the rate of glucose consumption decrease? c) What is the mechanistic...
