The gastrointestinal tract uses both chemical and mechanical digestion.
Mechanical digestion is the breakdown of food through chewing, mixing, or churning. Mechanical digestion occurs in the mouth and stomach. The food is physically torn apart through the teeth, tongue, stomach contractions, etc. This is counterpart to chemical digestion, where acids and other enzymes chemically pull apart the food.
no it dont enzymes breaks down the large molecules into small molecules
No digestion actually happens in the pancreas, but the pancreas does secret enzymes that help break down carbohydrates, proteins, and fats into the digestive system.
Digestive enzymes are contained in vesicles called lysosomes. They are produced by the Golgi body and dispose of worn-out organelles and carry out digestion.
Enzymes are also called biological catalysts. They speed up the rate of biochemical reactions. Metabolic processes such as digestion would take months to proceed without the help pf digestive enzymes.
yes
Mechanical Digestion happens in the mouth where your food is physically broken down. Chemical digestion happens in your intestines, where enzymes break down and absorb nutirients
Mechanical digestion chops the food in to smaller pieces, thus exposing more of it to the enzymes of the chemical digestion.Mechanical digestion begins in the mouth by the teeth, tongue and saliva. Mechanical digestion is important for chemical digestion because when food is broken down into smaller particles by mechanical means, chemical digestion will be more efficient.
Mechanical digestion is the same thing as chewing, or mastication. It does not need any digestive juices, because that is considered chemical digestion. Chemical digestion in the mouth during chewing is mainly by the aid of saliva which has, among other enzymes, salivary amylase which initiates carbohydrate digestion.
Digestive juices and enzymes break down food through chemical digestion.
cellulose. humans do not possess the enzymes necessary for its digestion.
Mechanical digestion is the physical mashing and pulling apart of food like chewing your food. Chemical digestion uses acids and enzymes to chemically break down the food until it is small enough to be absorbed through the wall of the small intestine.
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.
Digestive enzymes are in them.They involves in digestion.

The large intestine is mechanical digestion; it absorbs water and is involved in peristalsis. It has nothing to do with enzymes, which is chemical digestion.
think so
