Explain what molecule would serve as an electron donor and what would serve as an electron acceptor given E°' for each

Expert Solution

E° (standard reduction potential) of a compound represents the measurement of the tendency of receiving electron by the compound. A compound with more negative value of E° have greater tendency to donate electron and least tendency to receive electron. A compound with less negative or even positive E° value will have weak tendency to donate electron and greater tendency to receive electron.

Thus, a compound can be either electron donor or electron acceptor depending on the value of E° of other compounds in the reaction.

For example in the reaction couple 1/2 O2/ H2O, water (E° for hydrogen = 0.00) is electron donor and oxygen (E° = +1.23) is electron acceptor.

Without this molecule, cellular respiration does not happen, because it is the final electron acceptor. What is it? O2 water FADH2 CO2 Yeasts are single-celled eukaryotes that don't have a mitochondrion. Can they exist in an environment without oxygen? Yes, yeasts can exist in an oxygen-poor environment. They will only be able to produce 2 net ATP via fermentation, but the absence of oxygen will not kill the organisms. No, the presence of oxygen will kill yeast because they will...
