Microbial Metabolism

Question 1

Microbial metabolism

Answer 1

the buildup and breakdown of nutrients within a cell

Question 2

Drug manufacturing

Answer 2

Penicillin, vaccine, vitamins, enzymes

Question 3

Enzymes

Answer 3

act on a specific substrate; lower activation energy
-enzyme is unchanged after
-Lock & Key

Question 4

Reaction rate

Answer 4

altered by enzymes, temperature, pressure, concentration

Question 5

Factors Influencing Enzyme Activity

Answer 5

-Temperature
-pH
-Substrate concentration
-Inhibitors
(High temp and pH can denature proteins)

Question 6

Saturated substrate

Answer 6

enzyme catalyzes at its maximum rate
37℃=peak enzyme activity
>37℃=decreased activity

Question 7

Competitive Inhibitors

Answer 7

fill the active site of an enzyme and compete with the substrate

Question 8

Noncompetitive Inhibitors

Answer 8

interact with the allosteric site of the enzyme (allosteric inhibition)

Question 9

Feedback Inhibition

Answer 9

end-product of a reaction allosterically inhibits enzymes from earlier in the pathway, regulates amount

Question 10

Oxidation-Reduction Reactions

Answer 10

oxidation:removal of electrons
reduction: gain of electrons

Question 11

Redox reactions

Answer 11

oxidation reaction paired with a reduction reaction
(Kreb cycle, Electron Transport Chain)

Question 12

Oxidative Phosphorylation

Answer 12

Metabolic pathway
