Microbial Metabolism

Question 1

catabolism vs anabolism

Answer 1

breakdown vs buildup
provide energy vs uses energy

Question 2

Entropy high or low better

Answer 2

increase in entropy more favorable

Question 3

Which of the following groups is responsible for the vast majority of primary production on the planet?

Answer 3

it is estimated that each year, photoautotrophs (i.e., plants, algae and cyanobacteria) convert approximately 10% of Earth’s CO2 into biomass.

Question 4

What can the proton motive force power in the cell

Answer 4

The proton motive force can be used to drive secondary active transport, to produce ATP via ATP synthase, and to rotate bacterial flagella.

Question 5

Use of anything other than oxygen as the terminal electron acceptor in an electron transport chain is known as what?

Answer 5

anaerobic respiration

Question 6

What is the difference between bio augmentation and biostimulation

Answer 6

bioaugmentation: addition of microbes to promote biodegradation process, exogenous

biostimulation: adding electron acceptors, donors to nutrients to stimulate naturally occurring microbial populations, indigenous microorganisms

Question 7

bioremediation

Answer 7

use of microbes to remove pollutants or xenobiotics, occurs naturally

Question 8

Answer 8

integrase and reverse transcriptase
