Answer the following question given this paragraph: The biological electron transport chain provides for an orderly, stepwise transfer of electrons. Both NADH (reduced nicotinamide adenine dinucleotide) and FADH2 (reduced flavin adenine dinucleotide) are energyrich molecules that liberate a large amount of energy during oxidation. Free energy released during the transfer of electrons from either of these molecules to oxygen drives the synthesis of ATP (adenosine triphosphate) formed during respiratory metabolism. The reactions are as follows:. Q: The biological electron transport chain provides for an orderly, stepwise transfer of electrons. both nadh (reduced nicotinamide adenine dinucleotide) and fadh2 (reduced flavin adenine dinucleotide) are energy rich molecules that liberate a large amount of energy during what? Choices: - extrapolation - conduction - evaporation - oxidation A:
oxidation

Answer the following question given this paragraph: The type of atom is determined by the atomic number (i. e. the number of protons). The atomic mass of an atom is approximately the number of protons plus the number of neutrons. Typically, the atomic mass listed in a periodic table is an average, weighted by the natural abundances of different isotopes. Q: Adding the number of protons plus the number of neutrons in an atom, decides it's approximate mass, what is another word for this value? Choices: - electron count - atomic mass - real number - atomic number A:
**Answer**
atomic number
Q: Answer the following question given this paragraph: Carboxylic acids have high boiling points compared to other substances of comparable molar mass. Boiling points increase with molar mass. Q: Boiling points increase with which kind of mass? Choices: - lipid mass - universal mass - protons mass - molar mass A:
A: molar mass
