The answer is D. The degradation process is also called the condensation process. It is referred to as so because it involves the expunging of a water molecule as a product during the joining of a glycerol molecule and 3 fatty acid molecule to form a triglyceride. The opposite reaction, called a hydrolysis reaction, involves the breaking of the triglyceride bonds into fatty acids and glycerol. A water molecule is consumed in this process.
