Chapter 6 HW
Enzyme involved in DNA replication
DNA polymerase, Helicase, and Gyrase
stationary growth phase
Phase during which nutrient depletion and accumulation of wastes begin to slow cell growth such that the rate of cell increase equals the rate of cell death
increases urine acidity
The RN educates the patient about managing the urinary tract infection at home. She recommends increasing fluid intake and consuming cranberry juice. Consumption of cranberry juice?
vaccination
The RN may anticipate all of the following to be ordered for treatment of the urinary tract infection expect?
Alkaline pH
The patient asks the RN to describe the disease process of a urinary tract infection. The RN disease process of a urinary tract infection. The RN describes bacterial urea digestion and ammonium release. How does the RN most accurately describe the resultant pH following bacterial urine decomposition, facilitating pathogen growth?
lag phase
adjustment period during which cells are dividing slowly while they adjust to growth conditions
False
both human and bacterial cells divide by mitosis.
replicate
cell must ____ their DNA prior to cell division.
hydrolysis of GTP
energy used by SRP receptor
binary fission
most cultured bacteria tend to multiply by
Mesophile
most of the microbiota in the human body are classified as
death phase
nutrients are depleted, and waste levels are high; cells are dying at a steady exponential rate
exponential growth
phase during which cells are growing very quickly, at their maximum rate of cell division
increase
refrigeration will ______ the doubling time of most pathogens.
septum
the FtsZ protein is needed to form the
exponential growth
the phase of the bacterial growth curve during which bacterial population has briefest doubling time
Doubling
the time required for one complete cycle of binary fission is known as the ________ time of generation time.
Psychrophiles; very few are pathogenic to humans
what type of bacteria will grow in the refrigerator, and why is this usually not a concern?
