Q

Exotoxins vs Endotoxins

A

Exotoxins- Some Gram+ bacteria secrete protein toxins

Endotoxins- Some Gram- bacteria secrete fat/carb toxin, but not until the bacteria cell like E.coli dies.

Binary-fission

A

Asexual reproduction

29
Q

Conjugation

A

the process by which 2 bacteria cells bind together and one cell transfers Dna to the other cell through a sex pilus

30
Q

Transduction

A

When a virus obtains a small part of DNA from a host bacterial cell, then makes copies within the host cell, which then blows open to release a new virus

31
Q

Transformation

A

Occurs when bacteria takes DNA from its surrounding environment

32
Q

Cyanobacteria

A

use of photosynthesis, produce oxygen, blue-green algae live in water, provide food to both marine and fresh water ecosystems

33
Q

Fermentation

A

used in the food industry to make buttermilk, sour cream, cheeses etc

converts CO2 into methane gas

O2 is poisonous

A

Salt loving

uses salt to generate ATP(energy)

36
Q

Thermophile

A

High temps.

Found in volcanic vents or cracks in the ocean floor

37
Q

Plasmids

A

Some bacteria have plasmids- small circular, self-replicating loops of double strandid DNA

38
Q

Capsules and Pili

A

Many bacteria have capsules- a outer covering made of polysaccarides that keeps it from drying out or being engulfed in white blood cells.
Pili- are hairlike structures made of protein or hooks that help them attatch to their host
