If two species of bacteria use glucose as an electron donor, but species a uses oxygen as the final electron acceptor and species b uses nitrate, then how much glucose would species b need to use to generate the same amount of atp as species a? see section 26.3 (page 526) .

Species B would need about 60% more glucose to generate the same amount of ATP as species A. This is because molecular oxygen is a highly oxidizing agent and therefore, is an excellent electron acceptor compared to other less-oxidizing substances such as sulfate, nitrate or fumarate. 

Heat can be used to disrupt hydrogen bonds and non-polar hydrophobic interactions. This occurs because heatincreases the kinetic energy and causes the molecules to vibrate so rapidly and violently that the bonds are disrupted. The proteins in eggs denature and coagulate during cooking.
