Micro Lecture Test #2

Front 1

Generation time

Back 1

Time it takes for bacteria to grow in optimal conditions

Front 2

Generation time

Back 2

The counting of the cells

Front 3

Plate Count

Back 3

directly couning on the plate

Front 4

Optical Density

Back 4

Counting based on how clear the fluid is

Front 5

Direct Microscope count

Back 5

Counting on the microscope

Front 6

Growth Phases

Back 6

Lag- Inital statge..Lots of division
Log- Acitivity during growth
Stationary- Producing at the same rate they are dying
Death- Nutrients decline, reproduce slower than they die.

Front 7

Thermophiles

Back 7

Like increased temo 45-80c.

Front 8

mesophiles

Back 8

Human body temps- 20-50c

Front 9

Psychrophiles

Back 9

Cold temps- burried under ice

Front 10

Obligate Aerobe

Back 10

Must have O2

Front 11

Microaerophile

Back 11

Likes just a little less O2 in the environment

Front 12

Obligate Anaerobe

Back 12

Does not like any O2 in the environement

Front 13

Aerotolerant

Back 13

Does not mind O2 in the environment

Front 14

facultative Anaerobe

Back 14

Doesnt mind O2 in the environment but perfers O2.

Front 15

Capnophiles

Back 15

Grows better with with more than normal Co2 in the environment. 5% more.

Front 16

Why is O2 dangerous?

Back 16

Due to SOD turning Co2 into H2O2. A catalase then turns it into H20 + O2 to make it safe again.

Front 17

Acidophiles

Back 17

Like PH level between 0-5

Front 18

Neutrophiles

Back 18

Like PH level between 5-8

Front 19

Alkalinophiles

Back 19

Like PH level between 8-12

Front 20

Activity of H2O (AW0

Back 20

Foods with high water concentrate will spoil faster due to increase bacteria growth

Front 21

UV Light

Back 21

required by some organisms to live.

Front 22

UV safe or dangerous? WHY?

Back 22

Dangerous due to the fact that it kills DNA

Front 23

What is the hardest to kill?

Back 23

Endospores

Front 24

Basic Growth factors?

Back 24

CHNOPS, K, Mg, Fe, Ca, Mn, Zn, Cu

Front 25

Activation energy

Back 25

The amount of energy needed to bring molecules together to initate reactions.

Front 26

Concentration

Back 26

the # of enzymes per reaction impacts the time.

Front 27

PH Concentration

Back 27

Bell Cure.... the abily to have a range with the PH

Front 28

temp Concentration

Back 28

Curve with a Drop due to proteins being denatured at a certain temp

Front 29

Allosteric regulation

Back 29

how it physically affects the enzymes ability to work.

Front 30

Anabolism

Back 30

Building of new molecules

Front 31

catabolism

Back 31

Breaking down of molecules

Front 32

Catabolism 3 big stages

Back 32

Glycolysis, Kreb Cycle, and ETC

Front 33

Substrate level phosphorylation

Back 33

ATP is releasing a (P) and goes directly to the enzyme, enzyme can add that (P) to another molecule

Front 34

carrier Molecules

Back 34

NAD & FAD

Front 35

Oxidation

Back 35

Loss of electrons, gain of O2

Front 36

reduction

Back 36

Storing energy gain of electrons

Front 37

Use of NAD & FAD

Back 37

to break up glucose molecules for energy

Front 38

Oxidation formula of NAD & FAD

Back 38

NADH & FADH2

Front 39

Where does cellular respiration happen?

Back 39

Glycolysis happens in Cytoplasm
