Were does chemical digestion take place
Examples: digestion, fuels burning, cooking, washing etc.
Chemical digestion begins in the mouth with the secretion of saliva from three pairs of salivary glands. Saliva contains the digestive enzyme salivary amylase.
Saliva, amylase, mechanical and chemical digestion, muscles, mucus, stomach acid.
Chemical digestion and mechanical digestion
Its a chemical change.
No, the pancreas is involved in chemical digestion, as it secretes enzymes which catalyze the breakdown of food molecules.
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Mechanical Digestion (ex. chewing your food) and Chemical Digestion (ex. your spit breaking down the food). Those examples happen in the mouth, but both types happen elsewhere in the body, too.
the start of chemical digestion is the mouth and ends in the small intestine. This is true and the saliva has the power of the chemical digestion
Digestion can be mechanical or chemical. Mechanical digestion is the process of physically (i.e. not involving biochemical enzyme) breaking food down into smaller pieces, creating a greater surface area for chemical digestion to take place. Examples of mechanical digestion include the churning motion of your stomach and obviously, the chewing process of your mouth. Chemical digestion, on the other hand, requires the presences of enzymes to trigger chemical reaction and break the food particles down to simpler substances. Examples include the salivary amylase breaking down sugar, stomach acid and gastric enzymes breaking down proteins, and the lipase breaking down lipids in the small intestine.
Not sure what you mean by '3 types of digestion', but there are three major food groups (carbohydrates, proteins, and fats), and each has a different method of digestion by the digestive system.
