Question: Which Of The Following Is True About The Site Of Intracellular Digestion?

Which of the following is the site of intracellular digestion?

Lysosomes. Closely related to the Golgi apparatus are lysosomes. These membrane-bound organelles are the sites where most intracellular digestion occurs. They arise from and closely interact with the Golgi apparatus, and there is a brisk traffic of enzyme and membrane components between the two.

What is intracellular digestion?

intracellular: Intracellular digestion is a form of digestion which takes place within the cytoplasm of the organism. Intracellular digestion takes place in animals without a digestive tract, in which food items are brought into the cell for digestion.

What is intracellular digestion and give example of an organism showing intracellular digestion?

Occurrence. Most organisms that use intracellular digestion belong to Kingdom Protista, such as amoeba and paramecium. Amoeba uses pseudopodia to capture food for nutrition in a process called phagocytosis. Paramecium uses cilia in the oral groove to bring food into the mouth pore which goes to the gullet.

Which helps in intracellular digestion?

The primary sites of intracellular digestion are organelles known as the lysosomes, which are membrane-bounded compartments containing a variety of hydrolytic enzymes.

What is the difference between intracellular and extracellular digestion?

In intracellular digestion, the breakdown of food materials into small molecules occurs inside the food vacuoles within the cell. In extracellular digestion, the breakdown of food materials into small molecules occurs outside the cell in the lumen of the alimentary canal or on the decaying organic materials.

Is the site of intracellular digestion storage or transport?

Lysosomes Are the Principal Sites of Intracellular Digestion Lysosomes are membrane-enclosed compartments filled with hydrolytic enzymes that are used for the controlled intracellular digestion of macromolecules.

Do humans have intracellular digestion?

Digestion is the process of breaking down food into nutrients. Extracellular digestion takes place outside the cell. In humans, the digestive tract mechanically and chemically breaks down food so intestinal cells can absorb nutrients for the body. Intracellular digestion takes place inside the cell.

What are the 2 types of digestion?

Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.

What is extracellular digestion example?

In extracellular digestion, the materials or food particles are broken down chemically into smaller components outside the cell or onto the digestive system spaces. For example, fungi feed on their food by secreting digestive enzyme s to digest their food externally, which they later absorb.

What type of digestion occurs in humans?

Humans use extracellular digestion when they eat. Their teeth grind the food up, enzymes and acid in the stomach liquefy it, and additional enzymes in the small intestine break the food down into parts their cells can use.

What is difference between intracellular and intercellular?

Intercellular means ‘between two or more cells’ while intracellular means ‘ within a cell ‘.

What is extra and intracellular digestion?

extracellular digestion: Extracellular digestion is a process in which animals feed by secreting enzymes through the cell membrane onto the food. Intracellular digestion takes place in animals without a digestive tract, in which food items are brought into the cell for digestion.

Where digestion of cell nutrients takes place?

The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.

Do sponges have intracellular digestion?

Lacking a true digestive system, sponges depend on the intracellular digestive processes of their choanocytes for their energy intake. The limit of this type of digestion is that food particles must be smaller than individual cells. Sponges reproduce both sexually and asexually.
