Carbohydrates, proteins, and fats are processed in the intestine, broken down into their basic units to absorb and use your body for energy, growth, and cell repair.

Complete answer:
Option A is incorrect. Glycerol is a precursor in the liver and adipose tissue for the synthesis of triacylglycerols and phospholipids. As the body uses stored fat as a source of energy, this releases glycerol and fatty acids into the bloodstream.
Option B is incorrect. Amino acids and glycerol cannot be produced by the breakdown of carbohydrates and proteins, since glycerol is produced through the use of body fat as a source of energy is released into the bloodstream or provides energy for cellular metabolism.
Option C is correct. Carbohydrate digestion is converted into glucose (a monosaccharide), proteins are broken down into their basic units such as amino acids. And the fats are converted to fatty acids and glycerol.
Option D is incorrect. The final product of carbohydrate digestion is primarily glucose along with some fructose, glucose, and galactose, while amino acids are the end products of protein digestion throughout the small intestines.

So, the correct answer is Option C.

Additional Information:
Digestion is the breaking down of mechanical and chemical food into small organic fragments. Macromolecules need to be broken down into smaller fragments of the correct size for digestive epithelial absorption. A large, complex protein, polysaccharide, and lipid molecules have to be reduced to smaller particles like simple sugar before they can be consumed via the digestive epithelial cells. In the digestive phase, different organs perform unique roles. For a nutritious balance, the animal diet requires carbohydrates, protein, and fat, as well as vitamins and inorganic constituents.

Note: Monosaccharides (primarily glucose from carbohydrates); monoacylglycerol and long-chain fatty acids (from lipids); and small peptides and amino acids (from proteins) are the major ingested end products of food digestion. When in the bloodstream, certain nutrients may be metabolized by various cells.
