Answer 2

$\huge{ \bold{ \purple{ \mid{ \underline{ \overline{the \: acid \: is \: HCl}}}}}}$

━━━━━━━━━━━━━━━━━━━━━━

❋The stomach contains several branched and tubular glands present on the inner surface of its walls, These are known as Gastric glands.

❋ The gastric glands secretes gastric juice.

❋ The gastric juice contains :-

$\large{ \sf{ \star{hydrochloric \: acid(HCl)}}} \\ \\ \large{ \sf{ \star{enzyme \: pepsin( \: inactivated - pepsinogen)}}} \\ \\ \large{ \sf{ \star{mucus}}}$

$\large{ \sf{ \red{ \dag{ \underline{ \underline{ \: \: why \: acid \: is \: present}}}}}}$

❋ The HCl provides a acidic medium to inactive enzyme pepsinogen to get conveted to pepsin, the enzyme pepsin then begins the digestion of proteins into amino acid.

$\large{ \sf {proteins \: \: \green{ \underrightarrow {pepsin}} \: \: peptons \: + \: peptides}}$

❋ It also kills the bacteria and microbes inside food.

$\large{ \sf{ \red{ \dag{ \underline{ \underline{ \: \: how \: can \: acid \: present \: in \: stomach}}}}}}$

❋DON'T worry!!

The mucous inside stomach helps to protect the stomach wall from its own secretion of Hydrochloric acid. The proteins hence, starts to digest.
