Mutation Correct Answer-Mutation is a change in the DNA that can sometimes cause a change in the gene product, which is the target of the antimicrobial. Destruction or Inactivation Correct Answer-Many bacteria possess genes which produce enzymes that chemically degrade or deactivate the antimicrobial, rendering them ineffective against the bacterium. Efflux Correct Answer-Certain bacteria can often become resistant to antimicrobials through a mechanism known as Efflux. An efflux pump is es...

What are the 3 ways that drugs can be eliminated kidneys (urine) gallbladder (bile) gut (feces) What are the 2 ways that inducers induce CYP enzymes increase the expression of the gene sequence that codes for the enzyme (makes more of the enzyme present) increasing the activity of the enzyme (making it work faster) Enzyme inhibition occurs _____ and typically takes _____ to see effect. The same is true for its offset. fast; at most a few days Enzyme induction occurs __...

1 molecule of glucose can generate 38 molecules of ATP via aerobic respiration in prokaryotes. And why is it never the case in reality? - CORRECT ANSWERS--Glucose never generates 38 ATP in reality • The PMF generated from ETC is never used only to generate ATP • Bacteria spend some of their PMF energy to maintain stable ion gradients during extreme changes in external pH and oxygen levels • Bacterial also have other cell processes that use PMF directly. E.g. flagellar rotaAon,...

MTM-Final Exam Basic Science Ionized forms like A- and BH+ are ________ and ______ diffusible across membrane water; poorly generic equation used to calculate week acidic and basic drugs 10 ^(pka-pH) = protonated/unprotonated equation to calculate weak acidic drugs 10^(pka-pH) = [nonionized(HA)]/[ionized(A-)] equation to calculate weak basic drugs 10^(pka-pH) = [ionized (BH+)]/[nonionized(B0] if the pka and pH difference is 1 or -1: ionization is 90% or 10% if the pka and pH differe...

Microbiology Chapter Exam 1 Questions with 100% Correct Answers | Verified | Updated How is osmosis different from simple diffusion? - answerWater movement is driven by the concentration of solutes rather than its own concentration. Nonspecific permeases - answerallow a variety of molecules to cross the cytoplasm membrane What will happen to a cell that is placed in a solution containing a high concentration of sugar, a molecule that cannot pass across the cell membrane? - answerthe cell...
