It is because proteases work only on proteins.

What catalyst helps digest our food?

There are many different ones: amylases digest starches, proteases digest proteins, lipases digest fats, etc. in each of the main categories there are many different enzymes (biocatalysts) that act on specific things in that nutrient category.


In what structure do proteases first act on food?

Proteases act on food within the stomach. They break down proteins into amino acids by hydrolyzing peptide bonds. This process is a crucial step in the digestion of proteins.


Nutrient in which protease enzymes act on?

Proteases breaks-down proteins into peptides & amino acids


Where is the enzyme that breaks down proteins?

Digestion of protein starts from stomach. In stomach the proteolytic enzymes such as pepsin, trypsin, chymotrypsin are produced and act of proteins derived from food. But in general, an enzyme can break down proteins anywhere (in lab environment too) if there is optimal condition (such as buffer, pH) is provided.


What is historical act of scaling walls on ladders called?

The attack on the walls of a fortress using ladders is an Escalade.


What enzymes digest protein?

Enzymes dont digest proteins they act as cataylst to break down the protein, there is a difference. :D As one enzyme is specifc to one type of protein, there are a wide variety of them, For example. Amylose (in out saliva) is catalyst by amylase the enzyme. Lactose in dairy is cataylsed by the enzyme lactase. And Cellulose (in plant cell walls) is catalysted by Celluase.


A mass of interconnected cardiac muscle cells that act as a unit constitutes a what?

a mass of merging cardiac cells that act as a unit is called functional syncytium. two of these are in the heart (atrial walls, and ventricular walls)


What do bile salts do to digest fat?

Bile salts do not digest fats. They cause the fats to become smaller and that increases the surface area so that enzymes in the digestive tract can act quickly.

Why doesn't protease digest itself?

Good question, but once you think about it, the answer is quite simple. Protease needs to grab on to something (a protein) in order to digest it. It cannot grab onto itself. More specifically, proteases are designed to recognise specific proteins or protein sequences which they bind to and then cut or break up the protein at. The protease cannot turn around on itself in order to catalyse this reaction. This answer isn't quite correct. In your answer you act as if there is only one pepsin molecule. If that was the case then indeed pepsin cannot 'grab onto itself'. However the question should have been : why doesn't pepsin digest other pepsin molecules. To find the answer to that you would have to look closer into what kind of atoms the molecules are made of and why they do not 'react' with eachother.
