____________ is an end product of digestion of fat.

Explanation

The question is asking us to identify the end product of the digestion of fat. The options are glucose, fatty acid, amino acid, fructose, and galactose. Out of these options, the correct answer is fatty acid. When we eat food containing fat, our body breaks down the fat molecules into smaller molecules through a process called digestion. The first step of fat digestion occurs in the mouth and stomach, where the fat is emulsified by bile and broken down into smaller droplets. These droplets then enter the small intestine, where they are further broken down by enzymes called lipases. The end product of this digestion process is fatty acids. Fatty acids are a type of molecule that can be used by our body for energy or stored as fat in adipose tissue. They are also used to build cell membranes and to produce hormones. In summary, the correct answer to the question is option B: Fatty acid, as it is the end product of the digestion of fat.
