MICROBIOLOGY EXAM 3 RIO SALADO FINAL
PAPER 2026 STUDY GUIDE DETAILED ANSWERS
READY
◉ blocked penetration
Answer: the antiobioc becomes ineffective Bc it cannot get into the
bacteria
◉ inactivation
Answer: the antibiotic itself is modified which causes it not to be
able to interact with the larget molecule of the bacteria
◉ target mimicry
Answer: the microbe produces a molecule that is similar to the
target molecule for the antibiotic and the antibiotic binds to it
instead of the target molecule
◉ what is a physical method of microbial control used in perceived
foods?
Answer: osmotic pressure
◉ what would be affect by antibiotics that inhibit cell wall synthesis?
,Answer: bacteria and fungi
◉ what is the term for the treatment that suppress microbial
growth, but does not kill the population
Answer: bacteriostatic
◉ true or false: all germs are pathogenic
Answer: false
◉ Which of the following keeps most potential pathogens from
taking up residence in the body?
Answer: innate immunity
◉ Which of the following distinguishes physical from chemical
defenses?
Answer: Physical defenses keep microbes out, and chemical
defenses eliminate microbes.
◉ Which of the following would be low in a person undergoing
chemotherapy and at risk for infection?
Answer: leukocytes
◉ Which of the following would be the first step of phagocytosis?
,Answer: molecular recognition

membrane, they are probably which of the following?
Answer: mast cells

blood tests show they have an increased level of white blood cells
that are bi-lobed and have red granules?
Answer: protozoa
◉ Which of the following uses phagocytosis and extracellular
chemicals to kill bacteria?
