Expert Solution
Step 1
Most of the mechanical digestion occurs in the mouth (mastication and chewing) and stomach(grinding and mixing). The stomach also carries out a little portion of chemical digestion. The stomach secretes gastric juice which helps in chemical digestion through its contents ( pepsin, HCL, intrinsic factor, and mucus)
Protein is a polymer of aminoacids - amino acids linked by peptide bonds.
Protein digestion begins at the stomach.
