The Preamble to the Constitution begins with

When the compound on the left is converted to the compound on the right, what type of chemical change has occurred?     NAD+ + 2 H+ + 2 e- –> NADH + H+

The standard reduction potentials ( E°) for the following half reactions are:                Oxaloacetate + 2H+ + 2e- –>    malate                     E°  = –0.16 V             NAD+ + 2H+ + 2e-             –>     NADH +  H+          E°  = –0.32 V   (Remember by convention all half reactions are written as reductions.) Using the reduction potentials (E°) values given above, what is the

Why do humans make urea?

The Supreme Court ruled that individuals who are arrested must be informed of their constitutional rights in

Which of the following is/are CORRECT for both the pyruvate dehydrogenase complex and the alpha-ketoglutarate dehydrogenase complex?  

A phospholipid is hydrophobic and hydrophilic in nature

For the hypothetical metabolic pathway, A –> B  –> C –> D –> E, with the standard free energy changes for each step listed below, which step would you predict would be most highly regulated? 

Hydrogen bonds are formed between two hydrogen atoms

We discussed ethanol as a fuel derived from glucose by fermentation. Recall one molecule of glucose is converted into two molecules of ethanol. Two ethanols have a higher energy DENSITY (more energy per gram) than one glucose because:
