Question

please and thank you

Where are each of our macronutrients (carbohydrates, proteins and fats) chemically digested? Where does the process for each of them begin? Also note all locations in the GI tract that these processes continue (until each macronutrient has been broken down into components that our cells can absorb).

Answer 1

The answer to the question is as follows: Digestion & carbohydrates starts in mouth. • Saliva contains an enzyme salivary - amylase. at breakdown starch into maltose - Starch Salivary Amylase uygus Maltose Me 1 small intestine recieve the secretion & Bile juice and pancreatic juice. Pancreatic juice contain enzyme, pancreatic amylase which digest remaining starch into Maltose Maltose ý further breakdown into simple sugar by an enzyme maltase ñ intestinal juice Protein are digested by enzyme pepsin in gastric juice Pancreatic juice contains enzyme trypsin which further break down it into peptides. Enzyme Peptidase in intestinal suice breakdown peptides into amino acids Fats are emulsified by bile juice. Pancreatic lipase breakdown emulsified facts into fatty acid and glycerd. Intestinal quice has enzymes to breakdown carbohydrates into glucose , proteins into amino acid and fats into fatty acid and glycerol. an
