QUESTIONS AND ANSWERS | WITH COMPLETE SOLUTION.
element Answer - matter that is made up of a single type of atom
Paul Eurlich Answer - "magic bullet" idea for syphillis. Wanted to kill pathogen
but not patient.
snow Answer - epidemiology- studied outbreak of cholera>linked to a water
source and shit that water source down and the epidemic stopped
phagocytosis Answer - moving large solid material into the cell
pinocytosis Answer - moving liquid into the cell
eukaryotic lysosome Answer - in animal cells. "recycling bin". it breaks down
cell parts with enzymes. can destroy invading prokaryote and open into the
cytoplasm for "suicide"
EUKARYOTE VACUOLE Answer - storage for starch, lipids, water, etc. largest
organelle in cell. plants and algae.
eukaryote peroxisomes Answer - "toxin neutralizer" thats a specific lysosome.
enzymes destroy poisonous metabolic waste.
,eukaryotes chloroplast Answer - harvest light for photosynthesis. (2
phospholipid membranes) and THLAKOIDS which are membranous sacs
(pancake shaped) which contain pigments to ETC to convert light to ATP. Have
own DNA and ribosomes, make few proteins.
eukaryote mitochondria Answer - cellular respiration for animal cells. 2
phospholipid bilayers that has tiny folds inside (cristae ~~~) and cristae contain
ETC to convert chem energy to ATP. Have own DNA and ribosomes, make few
proteins.
EUKARYOTES FLAGELLUM Answer - moves by undulation not rotation.
structure is complex arrangement of tubulin. basal body and filament, but
surrounded by cell membrane.
structure:
-tubuin forms hollow tubes-> microtubules
-basal body:9+0 arrangement in triplets
-filament:9+2 arangment in pairs
proteins Answer - subunit: amino acids
covalent bond: peptide bonds
purpose: catalysts, structure, membrane, receptors, messengers.
elements: CHONS
virulence factors: extracellular enzymes Answer - secreted enzymes that aid in
pathogens survival in the host also for invasion. EX: hyaluronidase, collagenase.
3 types of reservoir of infection Answer - a site where pathogens are
maintained as a source of infection. *most can't survive off of host
, animal reservoir of infection Answer - (zoonoses: disease spread by animals)
transmitted by eating, contact with waste, biological (ticks etc)
human reservoir of infection Answer - asymptomatic, human has infectious
disease but doesn't have symptoms to show it so may unknowingly infect
others
NONLIVING reservoir of infection Answer - water, soil, food, fecal oral rout
bacteria cytoskeleton Answer - simple network of fibers under the cell
membrane for the cell shape. *not present in all bacteria
symbiosis Answer - two or more organisms of different species living together
archaea cell membrane Answer - function similar to bacteria. sometimes only
one layer, use different types of phospholipids than ll other organisms, fatty
acids can be branched, different covalent bond between fatty acid and glycerol.
atom Answer - smallest chemical unit of matter
pathogen Answer - each disease is caused by specific organisms
Senmelweis Answer - OBGYN who activated for hand washing in hospitals.
noticed more women died who gave birth in hospitals than who didn't and
deaths declined after implementing hand washing. was treated poorly for this
idea
eukaryote centrisome Answer - functions and is important in cel division of
many eukaryotes (mitosis and cytokenesis) 1: shape is 2 centrosomes at a right
