Lysosomes are organelles that contain powerful enzymes to assist in destroying cellular debris and the breakdown of proteins and lysozymes are one of the proteolytic enzymes found in lysosomes that catalyze (breakdown) the protein wall of bacteria, especially gram positive bacteria, making lysozymes a vital part of our first-line defense against bacterial infection. Dr. Winston Morrow
A lysosome is a membrane-bound organelle found in eukaryotic cells that contains enzymes responsible for breaking down cellular waste and debris. Lysozyme, on the other hand, is an enzyme found in tears, saliva, and mucus that helps protect the body by breaking down bacterial cell walls. The main difference is that lysosomes are organelles within cells, while lysozyme is an enzyme found outside of cells in bodily fluids.

Which linkage breaks lysozyme in bacterial cell wall?
Bacterial cell walls contain a layer of peptidoglycan, which is the specific site that lysozyme attacks.The layer contains alternating molecules called N-acetylglucosamine and N-acetylmuramic acid.These molecules form a strong chain that acts as the backbone for the cell wall. The link between the two is cleaved by lysozyme. Once this chain is broken by lysozyme, it results in bacterial death.
Why is Lysozyme is not effective against viruses?
Lysozyme works by damaging bacterial cell walls, causing them to rupture. Viruses do not have cell walls, so lysozyme cannot target or affect them in the same way it does bacteria. This is why lysozyme is not effective against viruses.
What antibacterial agent does saliva contain?
Saliva contains lysozyme, which is an antibacterial enzyme that helps protect the mouth from bacterial infections.
When does a lysosome membrane disintegrate?
A lysosome membrane can disintegrate when the lysosome is damaged or under conditions of cellular stress. This can lead to the release of digestive enzymes and contents of the lysosome into the cytoplasm, potentially causing cell damage or cell death.
The expulsion of lysosome enzymes into cell cytoplasm is known as what?
The expulsion of lysosome enzymes into the cell cytoplasm is known as lysosome leakage. This can occur due to lysosome damage, leading to release of enzymes that can potentially damage other cellular components and even trigger cell death pathways.

What is the secretion that kills bacteria?
Antibiotics are substances produced by certain microorganisms that can inhibit the growth of or destroy bacteria.
What can you test with Lysozyme?
basically...
What is the antimicrobial enzyme found in tears?
The antimicrobial enzyme found in tears is called lysozyme. It helps to protect the eyes from bacterial infections by breaking down the cell walls of certain bacteria.
What is the relationship between lysosome and Golgi?
golgi makes lysosomes. haven't you heard of Google?
What is Phagocytosis.?
Phagocytosis is the cellular process of engulfing solid particles by the cell membrane to form an internal phagosome, or "food vacuole." The phagosome is usually delivered to the lysosome, an organelle involved in the breakdown of cellular components, which fuses with the phagosome. ------------------------------------------- The process where a Phagocyte 'disposes' of a pathogen is called phagocytosis, when a bacteria attaches to a phagocyte, using ligands, The phagocyte forms Pseudopods (cytoplasmic arms) that envelope the pathogen, the Psuedopodia then fuse, creating a membrane, enclosing the pathogen forming a phagosome, this moves deeper within the cell to then form with a lysosome forming a phagolysosome (not really imaginitive naming i know, but scientists aren't known for their imaginative naming ). the lysosome contains enzymes (you guessed it, lysozyme) the lysozyme destroys the bacterial cell walls allowing hydrolytic enzymes to digest the rest of the pathogen.Sources : Collins AS Biology for AQA textbookPhagocytosis is a process by which certain living cells called phagocytes ingest other cells or particles
How do lysozyme and penicillin differ in their effect on cell walls?
Lysozyme is an enzyme that breaks down bacterial cell walls by degrading peptidoglycan, a major component of the cell wall. Penicillin, on the other hand, inhibits the synthesis of peptidoglycan, leading to weakened cell walls and bacterial death. Both lysozyme and penicillin target the cell wall, but they achieve this through different mechanisms.
Can lysosome be found in the cytoplasm?
Lysosome is an organell.So it can be found in cytoplasm.
What is the job in the cell lysosome?
What is the lysosome job in the animal cell?
What breaks down substances in a cell?
The lysosome.
What organelles is the trash can of the cell?
Lysosome, or vesicles or vacuoles.
