Vedclass · Answer

(D) Absorption is the process by which the end products of digestion pass through the intestinal mucosa into the blood or lymph.$1$. Simple Diffusion: Substances like glucose,amino acids,and some electrolytes like $Cl^-$ ions move from higher concentration to lower concentration.$2$. Facilitated Transport: Substances like fructose and some amino acids are absorbed with the help of carrier proteins.$3$. Active Transport: This occurs against the concentration gradient and requires energy $(ATP)$. Examples include amino acids,glucose,and $Na^+$ ions.$4$. Water Transport: Water is absorbed by osmosis based on the osmotic gradient.$5$. Fatty acids and glycerol: Being insoluble,they are first incorporated into small droplets called micelles,which move into the intestinal mucosa and are reformed into chylomicrons.
