The image below shows two different fatty acid molecules.  Molecule [B] has a trans double bond.  Molecule [A] would most likely be found in nature.    

The following molecule is the active ingredient in dark chocolate, known as theobromine and more commonly cocoa.  Which of the following atoms in this molecule is making an incorrect number of bonds?   

Detergent molecules consist of a small polar group and a long nonpolar tail.  These molecules are able to trap grease and help to wash it away because in water, they create spheres that are polar on the outside and nonpolar on the inside.  These spheres are known as

Ammonia decomposes into nitrogen and hydrogen gases by the following equation: NH3 (l)

Which type of reaction is shown here?   

In the correct order, the products of Glycolysis, the Citric Acid Cycle and the Electron Transport Chain are:

Compare the atoms Potassium (K) and Bromine (Cl) help to balance charges across membranes in the cell.  For K, the ionization energy is [IA] and the electron affinity is [EA] compared to Cl.   

Match each molecule to its correct organic family. A. CH3CH2CH2CH2CH3 B. CH3CH2OH C. CH3NH2 D. CH3CH2SH

Which term best describes the relatively small portion of the enzyme that is directly involved in the biochemical reaction being catalyzed?

By the time carbohydrates have passed through the stomach and intestines, they have been broken down into single sugars such as glucose.  At the same time fats that pass through the stomach and intestines have been broken down into fatty acids.  The image below shows various examples of fatty acids.  Briefly describe why glucose can diffuse directly into the blood and fatty acids cannot.
