Discuss protein metabolism and the use of proteins as an energy source.
Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.

Step 1
The role of protein metabolism that include synthesis of certain kinds of protein and further it undergo the process of protein broken down. The protein metabolism help to regulation of hormonal coordination and enzymes act as a protein to synthesis or regulation of cell function. The digestion of protein starts in stomach in the presence of enzyme pepsin and Hcl. Hcl provides acidic pH to denature the protein present in the food then pepsin breaks proteins into small polypeptides and amino acids. When this food which is mixed with pepsin and HCl (Chyme) reaches small intestine then sodium bicarbonate gets released from pancreas to neutralize the Hcl present in the Chyme. Pancreas also releases chymotrypsinogen, trypsinogen and elastase. Chymotrypsinogen and trypsinogen are inactive form.
