What is the Process that prevents or inhibits the growth of pathogenic organisms?
The process that prevents or inhibits the growth of pathogenic organisms is known as antimicrobial action. This can occur through various mechanisms, including the immune response, which utilizes white blood cells and antibodies to target and eliminate pathogens. Additionally, antimicrobial agents, such as antibiotics or antiseptics, can disrupt cellular processes in pathogens, preventing their replication and survival. Environmental factors like pH, temperature, and nutrient availability also play a crucial role in inhibiting pathogen growth.
Which term describes the process of killing pathogenic organisms or rendering them inactive?
Sterilization is the process of killing or inactivating pathogenic organisms to prevent their growth and reproduction. This is commonly done through the use of heat, chemicals, radiation, or filtration.
The process that destroys pathogenic organisms but is not always effective against spores and viruses is?
Disinfection
Define disinfection How does it differ from antisepsis?
Disinfection the process of destroying pathogenic organisms or rendering them inert. Disinfection differs from antisepsis in that its a method of disinfection using chemical solutions.
Why EDTA tube prevents clotting?
EDTA acts as a chelating agent, binding to calcium ions in the blood which are necessary for the clotting process. By removing calcium, EDTA prevents the activation of coagulation factors and thus inhibits blood clot formation in the tube.
How does salt prevent decay?
Salt helps prevent decay by drawing moisture out of food, which inhibits the growth of bacteria and microorganisms that cause decay. This process, known as osmosis, creates an environment that is less hospitable for these harmful organisms, preserving the food for longer periods of time.
What results from process of a pathogenic bacterium?
strep throats
What is the mechanism by which a protein that binds to an operator inhibits transcription?
When a protein binds to an operator, it blocks the RNA polymerase from binding to the promoter region of the gene. This prevents the transcription process from starting, leading to inhibition of gene expression.
Why does salt prevent apples from browning?
Salt prevents apples from browning because it inhibits the enzyme responsible for the oxidation process that causes the browning reaction. This enzyme, called polyphenol oxidase, requires oxygen to function, and salt helps block this reaction by reducing the oxygen available.
What is the process of destroying inhibiting pathogenic organisms?
Destroying pathogenic organisms involves using methods such as heat (e.g., boiling, autoclaving), chemicals (e.g., disinfectants, antibiotics), radiation (e.g., UV light, gamma rays), or physical means (e.g., filtration) to kill or inhibit their growth. The choice of method depends on the type of organism, the environment, and the desired level of destruction. It is important to follow proper protocols and guidelines to ensure effective disinfection or sterilization.
What is the effect of curing and salting food have microbes?
Curing and salting food create an inhospitable environment for many microbes by reducing moisture content and increasing salt concentration, which inhibits microbial growth and reproduction. This preservation method enhances food safety by preventing spoilage and pathogenic bacteria. Additionally, certain beneficial bacteria may thrive during the curing process, contributing to flavor development while suppressing harmful organisms. Overall, curing and salting effectively extend the shelf life of food by controlling microbial activity.
What was 'transformed' in Griffith's experiment?
In Griffith's experiment, non-pathogenic bacteria were transformed into pathogenic bacteria by being exposed to heat-killed pathogenic bacteria, a process now known as transformation. This led to the discovery of genetic material transfer between bacteria.
