QuestionAnswer
99 percent of cell weight is made up of six different elements These include all but which of the following Lithium
This biomolecule is especially important for its role in the structure of cell membranes and vesicles Phospholipids
Proteins are made up of many different amino acids joined by what type of bond peptide bond
This type of protein complexes with reactants to make biochemical reactions more energetically favorable Enzyme
This is the term for all the chemical reactions in a cell metabolism
This is the time between the same points of the life cycle between two successive generations Generation/ Doubling Time
Within the typical growth curve this phase is the point at which exponential growth occurs before plateauing off Log Phase
Highly reactive molecules that contain oxygen are normal byproducts of metabolism and cause damage over time are Reactive Oxygen Species
The __ region of a gene is the beginning of the gene where RNA polymerase binds to initiate transcription Promotor
Prokaryotes typically have __ origins of replication when duplicating DNA one
This type of Operon is usually expressed until a repressing transcription factor binds to shut off the gene Repressible operson
A ___ is any change in the DNA sequence which may be harmful beneficial or neutral mutation
Is responsible for adding new nucleotides to a growing DNA strand during Replication DNA Polymerase
Repairs gaps in the new DNA strand especially on the lagging strand DNA Ligase
Unzips the DNA prior to replication DNA Helicase
Is responsible for building the mRNA strand from the DNA template strand during Transcription RNA Polymerase
Converts hydrogen peroxide to H2O and O2 Its presence is also used for microbe identification Catalase
This process joins pyruvate to coenzyme A while producing one NADH and CO2 Transition Reaction
When there is not enough oxygen organisms can use this process to recycle NAD+ from NADH so that glycolysis can continue Fermentation
In this process the energetic molecules/ carriers produced in the other reactions are converted to ATP through the movement of ions across a membrane and the enzyme ATP synthase Electron Transport Chain
Initial step of metabolism (that we talked about) breaks glucose into two pyruvate molecules generating ATP and NADH while utilizing ATP Glycolysis
This step produces a large amount of NADH and FADH2 for use by the electron transport chain. Citric Acid Cycle (Krebs)
This level of microbial control reduces and / or destroys microbial load to safe public health levels Sanitization
The ebola virus frequently fatal and exotic is considered an bsl level 4 organism
__ discovered the first antibiotic in 1928 Alexander Fleming
An antibiotics ____ is the concentration of the drug that is both safe and effective for the patient. Therapeutic window
These antibiotics affect many different species of bacteria broad spectrum
The specific way an antibiotic affects the bacteria it targets is known as antibiotics mode of action
antibiotics that specifically target the cell membrane are especially useful for treating Gram - bacteria
These are specialized protein pumps in the cell walls of bacteria that grab antibiotics that have entered the bacteria and pump them back out efflux pumps
This is the term for any condition in which the normal structure or functions of an organism are damaged or impaired disease
This is the term for successful colonization of a host by a mircobe infection
The s & s characteristic of disease are called syndrome
Infectious diseases that are commonly aquired in hospitals are called Nosocomial Diseases
This is the number of cells or virions that are needed to cause an active infection in 50% of inoculated individuals ID50
An organisms ___ is its ability to cause disease; while its ___ describes the severity of the disease pathogenicity; virulence
Lytic Cycle 1. Attachment 2. Penetration 3. Biosynthesis 4. Maturation 5. Lysis
Lysogenic Cycle 1. Attachment 2. Penetration 3. Encoding 4. Dormancy *Stress* brings it to Biosynthesis
Prokaryotes are described as ubiquitous this means that they are everywhere
Human pathogens are typically classified as this type of symbiotic relationship parasitism
Many betaproteobacteria can be described as eutrophs meaning they need relatively high amounts of nutrients to survive
These bacteria are causative agents of a majority of stomach ulcers Helicobacter pylori
These corkscrew shaped bacteria that contain axial filament between their inner and outer membrane spirochete species
Proteobacteria and nonproteobacteria can both be dsecried as gram negative
This is the microorganism that is not normally pathogenic but can be with factors opportunistic pathogen
This bacterial genus is one of the most studied because it produces more toxins than any other genus Clostridium
Helminths are worms
Disease caused by fugus infections are called mycoses
bacteria replicate themselves via process of binary fission
you are bit by a tick carrying Lyme's Disease which you contract. This is an example of ___ transmission. Vector
The outer protein coat of a virus is called Capsid
Viruses do not effect (none of the above)
Diseases that spread from animal to human Zoonotic Diseases
___ viral transmission is when a virus spreads from host to host Vector
The person in the lab session before you sneezes spreading Flu A Later you catch the virus This is an example of ___ transmission Indirect
This type of ssRNA virus integrates its genome into the hosts DNA using the process of reverse transcription Retrovirus
The specificity of a virus for a specific host is called Viral Tropism
Most Viruses mutate at a ___ rate high
Protists Fungi and plants are part of which domain Eukarya
Which domain of life Bacillus anthracis belong to bacteria
Unicellular prokaryotes that have no known human pathogens and no peptidoglycan in their cell walls archaea
almost all viruses must be viewed with ___ because of their extremely small size Electron microscopy
These are small circular units of DNA that reside in the cytoplasm of cells plasmids
This term describes a bacterium that has multiple flagella lophotrichous
A streptococcus bacteria will appear under the microscope as chains of spheres
This organelle is the sight of cellular respiration and energy production in eukaryotes Mitochondria
This part of the bacteria is a hollow tube used to transfer genetic material between individuals F/Sex Pilus
__ are the sites of protein synthesis Ribosomes
___ is the site of protein processing and modification after proteins leave the ER Golgi Apparatus
