Chapter I1 IIntroduction Ito IMicrobes Iand ITheir IBuilding IBlocks I(McGraw IHill)-Homework
1. Which Iof Ithe Ifollowing Ichoices Iis Ia Icorrect Iway Ito Idenote Ithe Ibinomial Iname
Iof Ia Imicroorganism?
Multiple IChoice
• I I Staphylococcus IAureus I(correct Ianswer)
Explanation
The Ibinomial, Ior Iscientific Iname, Iof Ia Imicroorganism Imust Ibe Ityped Iin Iitalics Ior Iunderlined Iif
Ihandwritten. I In Iaddition, Ithe Ifirst Iletter Iof Ithe Igeneric Ipart Iof Ithe Iname Imust Ibe Icapitalized Iwhile
Ithe Ifirst Iletter Iof Ithe Ispecies Iname Iis Ilowercase.
2. Which Iof Ithe Ifollowing Iis Ia Imacromolecule Ithat Iassembles Iinto Ibilayers?
Multiple IChoice
• Phospholipid I(correct Ianswer)
• Nucleic Iacid
• Carbohydrate
• Protein
3. Please Iwatch Ithe Ivideo Ibelow, Iand Ithen Iuse Iwhat Iyou Ihave Ilearned Ifrom Ithe Ichapter Ito Ianswer
Ithe Iquestions, Idemonstrating Iyour Iunderstanding Iof Ibiofilms.
1.) What Iis Ia Ibiofilm?
• Free-floating Ibacteria Ithat Imove Ithrough Ithe Iblood Ito Iother Isites
• A Igroup Iof Ibacteria Ithat Iaccumulate Iin Ilayers Iand Isecrete Iprotective
extracellular Imaterial
I
• A Ilayer Iof Isugars Ithat Ipersist Ieven Iafter Ibacteria Ihave Ibeen Ikilled Iby Iantibiotics
• A Ibacterial Icell Ithat Isecretes Ian Iextensive Inetwork Iof Ifibers Iaround Iits Icell Iwall I Incorrect

2. ) IWhich Iof Ithe Ifollowing Iis Ian Iexample Iof Ia Ibiofilm Icommonly Ifound Iin Ithe Ihuman Ibody?
• Dental Iplaque ICorrect
• Salivary Isecretions
• Ear Iwax
• Yellow Ior Igreen Idischarge
3.) IWhy Iare Ibiofilms Iimportant Iin Iinfectious Idisease?
• Bacteria Iin Ibiofilms Iare Ioften Iprotected Ifrom Iantibiotics.
• Most Imicrobes Icannot Icause Idisease Iwithout Iother Imicrobes Ipresent.
• The Isecreted Iextracellular I"gunk" Iis Ihighly Idamaging Ito Itissues.
Explanation
Question I1: I Bacteria Iattach Ito Ia Isurface Iand Iexcrete Ia Isticky Iextracellular Isubstance. I Other Ispecies
Ican Ibe Irecruited Ito Ithe Ibiofilm, Iand Ithe Iresult Iis Ilayers Iof Imultiple Ispecies Iof Ibacterial Isurrounded Iby
Ia Iprotective Icoating.
Question I2: I Dental Iplaque Iis Ia Ibiofilm Ion Ithe Isurface Iof Iyour Iteeth!
Question I3: I Antibiotics Iare Ioften Iblocked Iby Ithe Iprotective Icoating Ifound Iin Ibiofilms. I Also,
Ibacteria Imay Iexpress Idifferent Igenes Iwhen Ithey Iare Ipart Iof Ia Ibiofilm Iand Ibecome Iless Isusceptible Ito
Iantimicrobial Idrugs.
4. Match Ithe Imacromolecules Ito Itheir Ifunction Iwithin Icells.
Major Istructural Icomponent Iof Icell Carbohydrates Correct
Iwalls IMajor Icomponent Iof Icell Lipids Correct
I membranes
Speed Iup Iand Ifacilitate Ichemical Ireactions Iwithin
Proteins Correct
Icells
Inheritance Iand Iexpression Iof Igenetic Itraits Nucleic Iacids Correct
Explanation
DNA Iand IRNA Iare Inucleic Iacids Iinvolved Iin Igenetics. I Enzymes Iare Iproteins Ithat Ispeed Iup Ichemical
Ireactions. I Phospholipids Imake Iup Ithe Ibulk Iof Ithe Icell Imembrane, Iand Iseveral Idifferent Itypes Iof
Icarbohydrates Imake Iup Ithe I cell Iwall Iin Iorganisms Ithat Ipossess Ione.
5. Microbes Iare Ifound Iin Iwhich Ihabitat(s)?
All Iof Ichoices Iare Icorrect I(Ocean, IEarth’s Icrust, Iand IHuman IBody)
