Micro Exam 2 Study Guide questions and answers (2025
2026 update) complete test (100% verified)
Fermentation often involves the reduction of ___________, which is a product of glycolysis. - ✔✔AN
pyruvate
What historical figure proposed chemotherapy as a way of treating disease? - ✔✔ANS Paul Ehrlich
What is synergism? - ✔✔ANS 2 drug's working together to create a greater out put
What is chemiosmosis? - ✔✔ANS Chemiosmosis - use of ion gradients to generate ATP, ATP is synthesize
utilizing energy released by the flow of ions down their electrochemical gradient across a membrane
Which class of antibiotics should not be taken internally? - ✔✔ANS Membrane injury agents because it wi
affect our cell walls
Enzymes lower the activation energy of chemical reactions. What effect does this lowering of EA have on
reaction? - ✔✔ANS by lowering the activation energy they speed up chemical reaction
Per glucose oxidized, how many NADH molecules are produced by the Krebs cycle? - ✔✔ANS 6
-note- per glucose that enters gycolysis, the kern cycle
produces:4CO2,6NADH,2FADH, and 2ATP
, Thinking about a bacterial growth curve, which phase of growth contains the healthiest members of th
population? - ✔✔ANS Log phase
Thinking about a bacterial growth curve, which phase(s) involve exponential changes in cell number?
✔✔ANS Log phase: binary fission occurring exponentially
Death phase: death rate is exponential
Can a plasmid spread antibiotic resistance from microbe to microbe? What kind of plasmid contains antibioti
resistance genes? - ✔✔ANS yes, all resistance plasmid
Which type of antibiotic resistance involves the production of ß-lactamase by the microbe? - ✔✔AN
penicillins; resistance to the cell wall inhibitors
Is oxygen required for glycolysis to occur? - ✔✔ANS no
All chemical reactions occurring in a microbe are its ____________________. - ✔✔ANS metabolism
If an antibiotic is only effective against one group of microbes is it a broad or narrow spectrum antibiotic?
✔✔ANS narrow spectrum antibiotics
What are the targets of the antibiotics that affect the bacterial ribosome? - ✔✔ANS 30s and 50s , small an
large subunits
If a molecule loses an electron has it been oxidized or reduced? - ✔✔ANS oxidized
What are three products of fermentation discussed in lecture? - ✔✔ANS 4 products of fermentation:
**swiss cheese: CO2 propionic acid
**cheddar cheese, yogurt, and soy sauce: lactic acid
**wine, beer: CO2 eithanol
**nail polish remover rubbing alcohol: acetone
