Digestive System

starches

Up your butt. And what kind of answer is that?? :P

Food normally becomes a shapeless mass as it is digested, although if you have swallowed something that you cannot digest, it will retain its shape.

Well, let me put this short and sweet: If there were no bacteria in your digestive tract, you wouldn't be able to digest much anything.

gastric acids enzymes

If you have appendicitis, you will be...

* Doubled up in pain * Vomiting * Reflexively contract your abdominal muscles when touched ("guarding"). * Exhibit rebound tenderness. (If you push firmly down on the affected area and quickly release, indicates an inflammation.)

The Porifera, or sponges

the answer is lysosomes i think

Cats, just like all other animals, digest food in their stomach. The stomach breaks down the food quickly and effectively in order to provide the rest of the body with energy and nutrients. House cats have the same digestion as wild cats do; they are efficient at breaking down and gaining all needed nutrients from fresh, raw meat.

It was considered not to have any use. Now it is thought to be a store of 'good' bacteria used to 'reboot' the digestive system after illness.

to become a astronaut you need a strong stomach. from what i learned.

cholecystokinin

I don't believe it does. in fact I think it can cause stomach noise. I have had awful stomach noises and been embarrassed in public so I stopped taking Metamucil and so far the sounds have stopped. Stomach nose comes from too much gas which can be caused by Metamucil or other foods.

Sucrase is the enzyme (called a disaccharidase) that digests sucrose, the major disaccharide in table sugar.

food must be digested cuz the food we ingest is not a form usable by our bodies. therefore digestion is necessary to break down food in its complex, insoluble, inorganic form to a simple, soluble, organic form

to seperate digestive system and respiratory system........adikshya...

Food molecules are pieces of food broken up by acid juices in the digestive system.

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.

The digestive system! they grind up the food and then the tongue pushes it into the throat and then... you know what happens next!right?

Cellulose is just a polysaccharide composed of glucose. If we had the digestive enzymes to break down cellulose into glucose, it would just mean tha we can get more energy from our diet without turning the cellulose into "roughage." Cows have a symbiotic relationship with certain kinds of bacteria that make the digestive enzymes. This is why cows and some other animals can break down cellulose and eat grass. If we had the enzymes to break down cellulose, we too would be able to eat grass!

The two enzymes differ based on where they cleave the protein being digested. The amino peptidase cleaves the protein from the amino terminus while the carboxypeptidase cleaves the protein from the carboxy terminus.

It means your poorly
