Vedclass · Answer

(D) In the human stomach,the gastric glands secrete gastric juice which contains $HCl$ and proenzymes like pepsinogen.$HCl$ provides an acidic medium with a $pH$ of approximately $1.8$ to $2.0$.This acidic $pH$ is essential for the activation of pepsinogen into its active form,pepsin.Pepsin is a proteolytic enzyme that breaks down proteins into proteoses and peptones.Therefore,the correct condition is an acidic $pH$ of $1.8-2.0$ for protein digestion.
