Its a chemical change.
Both chemical and physical change. physical:chewing food, making it into bolus, squeezing it through the esophagus. chemical: everything related to enzymes and change of composition, or breaking down stuff.
yes , during digestion carbohydrates are converted into simple sugar units,proteins into amino acids and so on, water and enzymes present in the body catalysed these reactions.
Both. Peristalsis takes place in the stomach and small intestine (physical digestion). Enzymes secreted in the stomach and small intestine are chemical digestion.
Its a chemical change.
Chemical Change
CHEMICAL
Digesting food is a chemical change.
both physical and chemical
Both
Both, It physically alters the excrement and chemically changes the nutrients.
Digestion involves both physical and chemical changes. The teeth crush food into smaller particles, which is a physical change, whereas the saliva, stomach, gall bladder, and pancreas contain chemicals that break down food chemically in the mouth, stomach, and small intestines.
Physical: Chewing to make the food particles smaller. Chemical: Reactions with enzymes to break down the food so the body can use it.
im not 100% sure but i believe its a chemical change mostly because a chemical change is when the molocules themselves change to create something else and physical is when the molocules only rearange themselves they don't change at all. seeing as how when you digest you do change whatever you have eaten by breaking it down with the acids in your stomach turning it into what comes out next.
It has both chemical and physical components Chewing, of course, is a physical process. Additionally enzymes in the saliva and stomach break down food chemically.
Medical digestion is the physical process of breaking down food Chemical digestion is the process of breaking down food by chemical enzyme.
it depends on how you look at it. its primarily chemical because without the chemicals in your body like pancreatic juices and hydrochloric acid, you could'nt break them down. but physically you chew your food before you swallow it for those chemical processes to occur. its safe to say however that the CHEMICAL part is absolutely essential for the proper digestion of food.
its a physical joking its a chemical change a physical is one substances, and a chemical change is two or more substances so the answer is to food molding a chemical change
Mechanical digestion. The actual grinding and physical breaking down of food. Chemical digestion breaks down food using chemicals/enyzyms and chemical reactions.
