Intro to bacteria

Nutritionaltypes

Pro. Vs. Eukcells and DNA

Chemistry Membranes

Kochs postulates explain this

What is if a certain organism is responsiblefor causing a disease

These organisms were the first to be described.

What are prokaryotes?

Microorganisms are not only responsible for causing diseases. They can also have beneficial

effects. These are some areas where microorganisms have beneficial effects.

What are agriculture (nitrogen fixing bacteria), energy and the environment

(bioremdiation), genetic engineering and positive effects on food (cheese, yogurt)

This is how the modern age ofbacteriology is different from the past

More is known about bacteria.Their DNA can be studied.

The evolution of bacteria can be studiedMolecular biology techniques can be used

There are different diseasesEtc.

These are two ways that can be used to culture microorganisms.

What is on agar in petri dishes or in a broth liquid culture?

These are organisms that use light as an energy source.

What are phototrophs?

These are organisms that use organic compounds as both the

carbon and energy source.

What are heterotrophs or chemoheterotrophs?(chemoorganotrophs)

These organisms use light as an energy source and organic compounds as

a carbon source

What are photoheterotrophs?

These compounds use inorganic compounds as

an energy source and CO2 as a carbon source.

What are lithoautotroph or lithotroph?

(chemolithotroph or chemoautotroph)

These organisms use light as an energy

source and CO2 as a carbon source.

What are photoautotrophs?

These are two different types of prokaryotes?

What are bacteria and archae?

These cells have a cytoskeleton.

What are eukaryotes?

These are 3 ways to categorize the DNA of bacteria

What is : DNA is found in the nucleoid region?

What is DNA is found in circular chromosomes?

What is there is less DNA?

What is the DNA does not have histones attached?

In these cells, transcription and translation are physically coupled; They

occur at the same time and the same place.

What are prokaryotes?

In eukaryotes, during cell division, and cytokinesis this is the name of the structure that separates one cell

into two cells.

What is a cell plate in plants and a cleavage furrough in animals?

These two groups form a peptide bond

What is amino and carboxyl?

These two groups form a glycosidic bond.

What is two OH groups?

This is the structure of an ether.

What is C-O-C?

This is the structure of an ester.

What is COO

In peptidoglycan, these are words usedto describe the glycosidic bond.

What is b 1,4?

These three molecules make up a phospholipid.

What are glycerol, fatty acids and phosphate?

This molecule is found in eukaryotic cell membranes but not

in prokaryotic

What are sterols?

These are three differences between bacteria/eukaryotic

membranes compared to archae membranes.

What are esters (bacteria/euk) vs. ethers (archae)?

What are fatty acid chains (bacteria/euk) vs. isoprene units (archae)?

What are glycerol diether and tetraether (archae)?

This is a type of transport mechanism where there are a series of proteins involved,

the substance transported is chemically altered during transport andthe energy involved usually comes from a

high energy phosphate bond (PEP)

What is group translocation or phosphotransferase-type

transporters?

In this type of transport mechanism, the protein transported first binds to proteins

in the periplasm of gram – bacteria;ATP provides energy for transport

What are ABC transporters?
