Extracellular digestion is a process in which saprobionts feed by secreting enzymes through the cell membrane onto the food. The enzymes catalyse the digestion of the food into molecules small enough to be taken up by passive diffusion, transport or phagocytosis. These nutrients are transferred into the blood or other body fluids. Since digestion occurs outside the cell, it is said to be extracellular. It takes place either in the lumen of the digestive system, in a gastric cavity or other digestive organ, or completely outside the body.
Extracellular digestion is a form of digestion found in all saprobiontic annelids, crustaceans, arthropods, lichens and chordates, including vertebrates.

Is earthworm digestion extracellular or intracellular?
It is extracellular
Which organism does not carry out extracellular digestion?
A cat is an example of an organism that doesn't carry out extracellular digestion. Parasites and fungi are examples of organisms that use extracellular digestion.
What is the advantage of extracellular digestion over intracellular digestion?
extracellular digestion enables and animal to digest much larger prey then intracellulary digestion allows.
Do mollusks undergo extracellular digestion or intracellular digestion?
Intracellular

What advantage is there to the extracellular digestion of cnidarians over the intracellular digestion of sponges?
nothing maufuddaah
Is intracellular or extracellular digestion is immediate energy?
intracellullar
Is centipede digestion extracellular or intracellular?
Centipede digestion is intracellular. They have a digestive system where food is broken down within specialized cells through intracellular processes.
Where is digestion held in the Monera Kingdom?
Digestion is extracellular (outside the cell) and nutrients are absorbed into the cell.
Examples of organisms that carry out extracellular digestion?
Fungi, such as mushrooms, carry out extracellular digestion. They secrete enzymes outside their bodies onto their food source, breaking it down into simpler compounds that can be absorbed. Some bacteria and insects, such as termites, also use extracellular digestion to break down complex materials like wood.
In which structure does extracellular chemical digestion of protein begin?
Stomach
How does bacteria and fungi digest food through extracellular digestion?
trying to be cool
