Prokaryotes: Growth and nutrients

HideShow resource information
Where does translation happen in the prokaryotes and eukaryotes?
Cytoplasm
1 of 18
Where does transcription happen in the prokaryotes and eukaryotes?
pro -Nucleus and euk - in cytoplasm coupled with translation
2 of 18
Explain some difference of prokaryotic and eukaryotic cells
Euk - nucleus contains DNA and membrane bound organelles, larger in size and more complex...... prok - dna is free, no organelles, all bacteria are prokaryotic
3 of 18
What are some requirements for growth of bacteria?
Environment, infections, fast evolution
4 of 18
Explain Binary fission
growth is rapid, parent cells divides into two daughter cells
5 of 18
what is catabolic reaction?
an metabolic reaction that is energy releasing - breaks molecular structures down
6 of 18
what is anabolic reactions?
an metabolic reaction that is energy requiring - uses energy to build larger molecules
7 of 18
What are the terms called with survive with or without oxygen?
Aerobes, facilitated anaerobes and anaerobes
8 of 18
What physica requirements are need for a baterica to survive?
temperature (different species like different temperature), pH ( most bacteria prefer pH7) and osmotic pressure
9 of 18
What is the lag phase in a bacterial growth curve?
First phase - synthesis of enzymes/nutrients. No growth
10 of 18
what is the growth phase in a bacterial growth curve?
Second phase - binary fission occurs
11 of 18
what is the stationary phase in a bacterial growth curve?
Third phase - nutrients drop and waste products rise
12 of 18
what is the death phase in a bacterial growth curve?
Final Phase -exhausted nutrient supply and toxic waste levels
13 of 18
How is bacterial growth measured?
most common indirect way is spectrophotometry
14 of 18
what are some limitations of spectrophotometry?
no indication of actual number of bacteria, doesn't tell you what organism it is or how many different types there are
15 of 18
What is good about spectrophotometry?
its excellent at manipulating th growth phase
16 of 18
What are bacteriophages?
a virus which parasitizes a bacterium by infecting it and reproducing inside it
17 of 18
What are the phases of the bacteriophages lifecycle
Attachment, biosynthesis, expression, assembly and release
