when activated lysosomes function in?
610551
Recent research suggests that lysosomes are organelles that store hydrolytic enzymes in an inactive state. The system is activated when a lysosome fuses with another particular organelle to form a 'hybrid structure' where the digestive reactions occur under acid (about pH 5.0) conditions.

You will find organelles called lysosomes in nearly every animal-like eukaryotic cell. Lysosomes hold enzymes that were created by the cell.

Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.

Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes. ... Rough ER: As membrane proteins grow from ribosomes on rough ER, the proteins are embedded into the rough ER membrane.

Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells. The lysosomes are the animal cell's “garbage disposal”, while in plant cells the same function takes place in vacuoles.

The enzymatic or hormonal contents of lysosomes, peroxisomes and secretory vesicles are packaged in membrane-bound vesicles at the periphery of the Golgi apparatus. Lysosome: Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells.

Lysosomes – Found throughout cytoplasm. Contains digestive enzymes that digest and destroy old cells, bacteria and foreign materials.

Lysosomes are digestive bags of the cell and Plastid is a cell organelle which contains chloroplast and leucoplast which give colour to the plant.

Lysosomes (lysosome: from the Greek: lysis; loosen and soma; body) are found in nearly all animal and plant cells. In plant cells vacuoles can carry out lysosomal functions. Lysosomes appear initially as spherical bodies about 50-70nm in diameter and are bounded by a single membrane.

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

The function of phagocytosis is to ingest solid particles into the cell. Phagocytosis is a type of endocytosis, which is when cells ingest molecules via active transport as opposed to molecules passively diffusing through a cell membrane.

The main difference between autophagy and phagocytosis is that autophagy occurs when lysosomes are fused with autophagosomes in order to digest the dysfunctional structures of the cell taken into autophagosomes whereas phagocytosis occurs when a foreign substance is engulfed by the cell, forming a vacuole called ...

Phagocytes act by migrating to infected areas and by ingesting and killing micro-organisms. NATURAL KILLER CELLS induce APOPTOSIS in virus-infected or tumour cells. MACROPHAGES remove apoptotic and aged cells.

Nutrient Acquisition and Digestion Amoebas obtain food by capturing their prey with their pseudopodia. ... Organelles known as lysosomes fuse with the vacuole releasing digestive enzymes inside the vacuole. Nutrients are obtained as the enzymes digest the food inside the vacuole.

Lysosomes are found in all animal cells, but are rarely found within plant cells due to the tough cell wall surrounding a plant cell that keeps out foreign substances.

Lysosomes are particularly abundant in secretory cells e.g. epithelial cells, and in phagocytic cells. For example, there are many lysosomes in liver cells - two of the main functions of the liver being (1.) secretion of bile and bile salts, and (2.) phagocytosis of bacteria and dead or foreign materials.
