Fermentation and anaerobic respiration terms

Question 1

alcoholic fermentation

Answer 1

The form of fermentation in which ethanol is produced as a product of NADH oxidation.

Question 2

anaerobic respiration

Answer 2

The form of cellular respiration in which substances other than molecular oxygen, such as carbon dioxide, sulfate, iron, or nitrate, are used as the terminal electron acceptor.

Question 3

chemolithotroph

Answer 3

An organism that oxidizes inorganic compounds to yield energy.

Question 4

facultative anaerobe

Answer 4

An organism that can live in either an aerobic or an anaerobic environment.

Question 5

fermentation

Answer 5

A biochemical pathway that allows NAD+ to be regenerated from NADH after glycolysis when an electron transport chain is not available. Known pathways include lactic acid fermentation and alcoholic fermentation.

Question 6

glycolysis

Answer 6

The biochemical process by which glucose is broken down into two molecules of the 3-carbon compound pyruvate.

Question 7

lactic acid fermentation

Answer 7

The form of fermentation in which lactic acid is produced as a product of NADH oxidation.

Question 8

obligate aerobe

Answer 8

An organism that can survive and thrive only in the presence of oxygen.

Question 9

obligate anaerobe

Answer 9

An organism that cannot survive in the presence of oxygen; an oxygen environment may be toxic to some members of this group.
