A. Free fatty acid absorption occurs in the small intestine.
Explanation:
Lipid digestion occurs with the help of bile juice and enzymes in the small intestine. The final products of lipid digestion are free fatty acids and monoacylglycerols. These two compounds enter the epithelial cells of the lining of the small intestine.
Once inside the epithelial cells of the small intestine, these two form the triacylglycerols again. Packing of triacylglycerols into chylomicron occurs in the epithelial cells of the lining of small intestine followed by their release into the blood via interstitial fluid and lymph.
Universe's average temperature and rate of expansion support the idea that it began as one super-dense and hot mass 13.8 billion years ago.
