Q

What are Koch’s postulates?

A

Causative agent found
Agent must be isolated and grown outside the host
When agent is introduced into a healthy host, the host must get the disease
The same agent must be re-isolated from experimental host

21
Q

Anabolism

A

Taking small molecules and building them up and creating larger molecules
Requires ATP

22
Q

Catabolism

A

Taking larger molecules and break them apart

All this with the purpose of releasing energy in the for of ATP

23
Q

Enzymes

A 
Very specific
Lock and key fashion
Decrease the activate energy needed for the reaction
Therefore speeding the reaction 
Re-usable
24
Q

Competitive inhibitor

A

Compete for the same binding (ACTIVE) site

25
Q

Non-competitive

A

Binds to another side other than the ACTIVE site

26
Q

ATP

A

Adenine triphosphate

27
Q

ADP

A

ATP after they’ve lost the phosphate

28
Q

Substrate level phosphorylation

A

A phosphate is transferred from some molecule to ADP to create ATP

29
Q

Oxidative Phosphorylation

A

Phosphate is added to ADP through series of REDOX reactions

Occurring during a respiratory pathway

30
Q

Photophosphorylation

A

Phosphate is added to ADP to make ATP

All this using energy from the sun

31
Q

What are the five I’s

A 
Inoculation
Incubation
Isolation
Inspection
Identification
32
Q

34
Q

Glycolysis

A

Break down of sugars
Takes place in the cytoplasm
Does not require oxygen

35
Q

Similarities between Prokaryotes and Eukaryotes

A

Posses genetic information
Presence of ribosomes
Plasma membrane
Cytoplasm

36
Q

Parasites

A

Harbored and nourished by the host

Always harmful to the host

37
Q

Biofilm Infections

A 
Attach to the surface 
Cemented by sugars secreted by the bacteria
Very difficult to dislodge
Ear, prostate, and lung infections
Heart valves and artificial joints
