Question

Give reasons
(1) Mucus is secreated along with hydrochloric acid in stomach?

(2) When a sports men runs he gets muscles cramp?

Answer 1

Hey mate

Mucus is a sticky substance which is secreted along hcl acid

The pro enzyme pepsinogen on exposure of hcl acid gets converted into active enzyme pepsin

The Mucus and bicarbonates present in gastric acid play an important role in lubrication and protection of mucosal epithelium from excoriation by highly concentrated hydrochloric acid

Answer 2

Answer:

hi

this is a nice questions

ok so here is the answer

while a sports man is running he breathes heavily as his stamina decreases

=> so the demand of oxygen is less for him

=>now he stars breathing anoerabically

=>during this  The muscles begin to do anaerobic respiration, because oxygen is not present.

=>now lactic acid gets accumalted in the muscles.this process is  lactic acid fermenation

=> it is a process that takes place when oxygen  is not present .

=>this causes muscle cramps when sportsman run

hope it helps u.......
