Bacteria Flashcards
Bacteria which grow and multiply in the marine sediments
Barophilic Prokaryotes ( mostly archae)
Bacteria are sole member of
Monera
Bacteria are – in structure but – in behaviour
Complex
Simple
Except – all monera have cell wall
Mycoplasma
In myco plasma cell wall is
Absent
In bacteria cell wall is made up of
Peptidoglycan or murein
Peptidoglycan is made up of alternating molecules of
NAM
NAG
Which bond joins NAM and NAG
Peptide
NAM
N acetyl muramic Acid
NAG
N acetyl Glucosamine
Name an amino acid exclusively found in gram positive bacteria
L lysine

In RK bacteria cell wall is made up of
Complex polysaccharide and populates polypeptide/ Pseudomurein 
In bacteria cell membrane is made up of
Lipoproteins
In place of cholesterol bacterial membrane contains
Hopanoid
Space between cell wall and Cell membrane
Periplasmic space
A part analogous to lysosome in bacteria
Periplasmic space
Name three amino acids found in both gram-negative and gram-positive bacteria

- D Glutamate
Cytoplasmic streaming
Cyclosis
In bacterial cytoplasm microtubules are 
Absent

In prokaryotic flagella is made up of which protein
Flagellin
In eukaryotes ,flagella is made up of which protein
Tubulin
Living cell was discovered for the first time by
Anton Von Leeuwenhoek
Father of Antiseptic Surgery
Lister
Name two techniques given by Lister
- Sterilization
- Artificial Culture
Germ theory was given by
Pasteur
Spherical bacteria
Coccus

Coccus
Endospore bacteria
Bacillus
Flagella all over the body
Peritrichous
Flagella in tufts
Lophotrichous
Two flagella on the either side
Amphitrichous
No flagella
Atrichous
Three parts of flagella
- Basal Body
- Hook
- Filament
Thickest part of flagella
Hook
Rod like part of flagella
Basal Body
Embedded part of flagella
Basal Body
Longest part of flagella
Filament
Four rings of basal body of flagella
L
P
S
M
Ring is present in gram positive bacteria
S
M
Which pair of rings is absent in gram positive bacteria
Outer pair
Rings in cell wall
L P
Rings in cell membrane

M
Ring in Periplasmic Space
S
Pili is made up of
Pilin protein
Does Pilli help in locomotion
Nooioiooo
Longer pili is also called
Sex Pili
Function of sex Pilli
Helps in conjugation
Pili is (contractile / non contractile)
Non contractile
Shorter pilli is also called
Fimbria , Infective Pili
Function of infective Pili
Helps in attachment with post
Bacteria has a chemically complex –
Cell Envelope
Cell envelope consist of – layers which our – arranged
3 ( three)
Tightly
Although each layer has its unique function but together they act as a –
Single Protective Unit
Mucilaginous layer around cell wall
Glycocalyx
Three layers of cell envelope
Glycocalyx
Cell Wall
Cell Membrane
Two forma of Glycocalyx
Slime Layer
Capsule
Slime Layer here is made up of
Polysaccharides
Capsule is made up of
Polysaccharides and Polypeptides
Loosely arranged layer of Glycocalyx
Slime Layer
Tightly arranged layer of Glycocalyx
Capsule
Function of Slime Layer
Helps in attachment
Function of capsule
Provide protection against phagocytosis
Capsule is pathogenic / non - pathogenic
Pathogenic
Thinner layer of Glycocalyx
Slime Layer
Thicker layer of Glycocalyx
Capsule
In gram-positive bacteria cell wall is
Unilayered made up of Peptidoglycan
In gram negative bacteria , cell wall is-
Bilayered
Outer layer of gram negative bacteria is made up of
Lipopolysaccharides
Gram positive bacteria has a thin layer of which acid
Teichoic Acid
What helps in intake of minerals in gram positive bacteria
Porin
