What protects food from entering the larynx?
Paul [167]
The epiglottis is a flap in the back of your tongue that prevents food from entering the larynx. When your mouth is closed, the epiglottis is in place and blocks the larynx opening. If your mouth is open, the flap lifts and the larynx is no longer blocked so you can breathe. This is why it's important to not chew with your mouth open... if you do, then food can go down the larynx by mistake.

The bovine pancreatic trypsin inhibitor comprises of 58 amino acids this consists of the disulphide bonds which are destroyed on heating as a result of this the inhibitor becomes inactive. But on cooling it comes to the original form as the internal structure starts making hydrogen and disulphide bonds again. Thus the activity of the BPTI again gets restored.
