MICROBIOLOGY EXAM 1 MATERIAL
QUESTIONS WITH 100% CORRECT
ANSWERS { GRADED A+}
what are some examples of acellular microorganisms? - ✔✔prion and
viruses
what are some examples of cellular microorganisms? - ✔✔bacteria and
eukaryote
what are the 3 different categories of positive roles of microbes? -
✔✔environmental benefits, food production, and medical benefits
what are examples of the environmental benefits of microbes? -
✔✔decomposition, bioremediation (intentional use of microbes to
break down human waste, toxic waste and pollutants), nitrogen fixation
,(certain bacteria fix nitrogen by removing nitrogen gas from the air and
converting it into nitrogencontaining compounds. plant proteins can be
consumed by plants and animals). photosyntesis (carbon fixation,
taking it out of air to create oxygen ie: algae)
what are examples of positive roles of microbes in food production? -
✔✔- cheese curding
- wine-- fermentation and the creation of bubbles
- beer-- it is molted where grain is layed and warm; microbes breeak it
down to create beer
- bread-- pockets of air, CO2 makes bread rise
- yogart, sour cream, and milk contain lactic acid which curdles milk
proteins
- cheese, vinegar, soy sauce, chocolate, sauerkraut
, what are examples of positive roles of microbes for health benefits? -
✔✔- microbiome-- microorganisms that live in the body; helps digest
food, produce vitamins, and protect us from harmful microbes
- biotechnology-- medications to treat disease ie: antibiotics, human
insulin, vaccines
commensalism - ✔✔one of organisms in the relationship (microbe)
benefits from the interaction while the other (human) is unaffected.
this is one of the relationship types for a resident microbe
mutualism - ✔✔both organisms (microbe and human) benefit from the
interaction. this is one of the relationship types for a resident microbe
where does your microbiome come from? - ✔✔in the utero, birth, milk,
caregivers, and the enviroment
pathogens/pathogenic microbes - ✔✔have a parasitic (one organism
benefits at the expense of the other) relationship with the human host
disease - ✔✔any deviation from a state of health
