that can be the final electron acceptor in aerobic ..

RESPIRATION: AEROBIC AND ANAEROBIC7) Define Respiration: Aerobic or anaerobic catabolic processesin which organic or inorganic electron donors are oxidized using oxygen(or an oxygen substitute) as the final electron acceptor.

Anaerobic respiration: respiration that uses substances otherthan O2 as a final electron acceptor

The diagram below of aerobic respiration (Figure 13) integratesthesemetabolic processes into a scheme that represents the overall processofrespiratory metabolism. A substrate such as glucose is completelyoxidizedto to CO2 by the combined pathways of glycolysis and the TCAcycle. Electrons removed from the glucose by NAD are fed into the ETSinthe membrane. As the electrons traverse the ETS, a pmf becomesestablishedacross the membrane. The electrons eventually reduce an outsideelectronacceptor, O2, and reduce it to H2O. The pmf onthemembrane is used by the ATPase enzyme to synthesize ATP by a processreferredto as "oxidative phosphorylation".

It is the final electron acceptor

b) Other microorganisms use succinate as an electron donor fortheir catabolic processes.

3) Define Fermentation: An anaerobic catabolic process consistingof internally balanced redox reactions, in which organic molecules serveas both electron donors and electron acceptors.

The final electron acceptor of cellular respiration is _____

The reducing poweris in the form of electrons carried in NADH and FADH, which are producedin the TCA cycle and passed to a membrane-bound electron transport system(ETS) terminated by oxygen (aerobic respiration) or another electron acceptor(anaerobic respiration).

– The final electron acceptor is usually an inorganic ..

A shows aerobic respiration, because O2 is the terminalelectron acceptor; B shows anaerobic respiration because NO3- is the terminalelectron acceptor.b) What is the function of the molecules labeled "Q"? As they acceptelectrons from one the previous electron carrier and give them up to thenext carrier, quinone molecules also move protons across the membrane,outside the cell.

needed as the final electron acceptor: ..

Respiration in some procaryotes is possible using electron acceptorsother than oxygen (O2). This type of respiration in theabsenceof oxygen is referred to as anaerobic respiration. Althoughanaerobicrespiration is more complicated than the foregoing statement, in itssimplestform it represents the substitution or use of some compound otherthanO2 as a final electron acceptor in the electron transportchain.Electron acceptors used by procaryotes for respiration ormethanogenesis(an analogous type of energy generation in archaea) are described inthetable below.

get transferred to final electron acceptor;

glycolysis does not provide as much energy as aerobic respiration, indeed in aerobic
respiration, pyruvate produced by glycoslysis is further oxidised by the Kreb's cycle and by the ETS, involving oxygen as the
final oxidant or terminal electron acceptor.
