Which enzyme in tears kills germs?
Your tears contain the enzyme lysozyme. This enzyme acts by disrupting the cell-walls of gram-positive bacteria by digesting the peptidoglycan in them, thereby preventing infection. This enzyme is also found in your saliva and is an example of a non-specific immune response.
How do tears act as barriers against harmful organisms?
Human tears contain the enzyme lysozyme which disrupts the cell walls of gram-positive bacteria by digesting the peptidoglycan in it. This enzyme can also be found in your saliva.
How do tears fight against pathogens?
True A+
Tears contain antibacterial substances that destroy many bacteria?
Basic a level knowledge: Tears are a form of chemical barrier from infection. The enzyme lysozyme is found in tears which kills of some bacteria which helps prevent pathogens entering the body and causing infection. I hope this helps, I'm unsure how the enzyme kills the bacteria as I was only aware that enzymes are catalysts that lower the activation energy in a reaction. If any one knows I'll be very grateful. :) Xxx

How do tears kill bacteria?
The lacrimal puncta/canaliculi/sac & hasolacrimal duct in the eye & accessory structures secrete and contain lysozyme which is an antibacterial enzyme(naturally occurring in tears). due to its acidity its responsible for killing some bacteria.
Is tears a chemical barrier against pathogens?
yes, tears prevent pathogens from entering the eye. when an irritation occurs the eye produces a salty liquid (tears) to clean the eye from any dust or pathogens. eyelashes also prevent pathogens and dust from entering. In terms of a chemical barrier, your tears contain the enzyme lysozyme which can disrupt the cell walls of gram-positive bacteria by digesting the peptidoglycan in them. This enzyme is also found in your saliva.
What is the antimicrobial enzyme found in tears?

What Vitamin is necessary for the production of an enzyme found in tears?
