|
Sterlization
|
The removal or destruction of all living microorganisms from a growth medium or surface
|
|
|
Decontamination
|
Treating a surface/object to make it safe to handle
|
|
|
Bactericide
|
Treatment that kills bacteria
|
|
|
Bacteriostasis
|
Treatment that inhibits growth/reproduction of bacteria but does not kill them
|
|
|
Antimicrobial agents
|
Chemicals that kill or inhibit the growth of microorganisms
|
|
|
Disinfectants
|
Chemical agents that kill microbes but are not safe for use on living tissues
|
|
|
Antiseptics
|
Chemical agents that kill microbes but are harmless enough to apply to living tissues
|
|
|
Sterilants/sterilizers
|
- Chemicals that destroy all forms of microbial life including endospores
- Applied in specialized gas chambers - Used to sterilize a wide range of plastics |
|
|
Enzymes
|
- Are proteins
- Are catalysts to chemical reactions - Highly specific - Have an active site |
|
|
Apoenzyme
|
It's the non-active, protein component of an enzyme
|
|
|
Cofactor
|
It's the non-protein component of an enzyme that has two parts: coenzyme & inorganic
|
|
|
Competitive inhibitors
|
- Type of inhibitor
- Bind to/block the active site - Compete with substrate - Shape/chemical structure is similar to substrate |
|
|
Noncompetitive inhibitor
|
- Type of inhibitor
- Bind to another part (allosteric inhibition) - Change the shape of enzyme/active site = inactivate it - Do not bond to active site |
|
|
Feedback inhibitions
|
- allosteric inhibition
- end product if a series of several enzymatic reactions stops reactions from occurring - once have enough product, stops cell from wasting resources making more product it doesn't need |
