Microbes and Energy Flow

Question 1

What is the identificator molecule used for bacterial classification?

Answer 1

16S rRNA gene

Question 2

This is formed when individual microbial cells of a species proliferate

Answer 2

Population

Question 3

This is formed when populations interact/communicate

Answer 3

Communities

Question 4

This is the study of interrelationships among organisms and their environment.

Answer 4

Microbial Ecology

Question 5

This is all microorganisms and their genes within a particular environment.

Answer 5

Microbiome

Question 6

This is when favourable conditions are induced to encourage growth of specific groups of microbes.

Answer 6

Enrichment culture

Question 7

This is the basis for energy transfer in all cells. This controls the flow of energy as well as the breakdown/buildup of molecules.

Answer 7

Reduction oxidation REDOX

Question 8

Energy harvested from environment is converted to a _______ inside the cell

Answer 8

Local currency

Question 9

These serve as intermediates to transfer energy inside of cell.

Answer 9

NADH/NADPH

Question 10

These facilitate redox reactions without being consumed. They are recycled.

Answer 10

NAD+ and NADH

Question 11

What are the four key trophic groups?

Answer 11

Chemoautotrophs
Chemoheterotrophs
Photoautotrophs
Photoheterotrophs

Question 12

These are known to fix CO2, they are self nourishing and are the PRIMARY PRODUCERS

• do not REQUIRE CO2

Answer 12

Autotrophs (CH2O—->CO2)

Question 13

These are dependent on primary producers. Need fixed carbon but cannot use CO2 directly

DECOMPOSERS

Answer 13

Heterotrophs

Question 14

These have complementary absorption spectra.

Answer 14

Photosynthetic pigments

Question 15

How do different microbes share the same metabolisms?

Answer 15

By tuning their antenna to a different wavelength. Having structures that enable them to capture light under low/higher intensities

Question 16

Different redox gradients selects for….

Answer 16

Different microbes
