Cellular Respiration and Fermentation

Question 1

Fermentation

Answer 1

a catabolic process where sugar is degraded or other organic fuel that occurs without the use of oxygen

Question 2

Aerobic respiration

Answer 2

oxygen is consumed as a reactant along with organic fuel to produce energy

Question 3

cellular respiration

Answer 3

the aerobic process of reactants the harvest chemical energy without oxygen

Question 4

Redox Reactions

Answer 4

The transfer of one or more electrons from one reactant to another
Loss of e- is oxidation and reduction is addition of e-

Question 5

Electron Transport Chain

Answer 5

a number of molecules built built into an inner membrane of the mitochondria of eukaryotic cells that move electrons and produce energy via pathways

Question 6

Stages of Cellular Respiration

Answer 6

1. glycolysis
2. pyruvate oxidation and citric acid cycle
3. oxidative phosphorylation

Question 7

Glycolysis

Answer 7

occurs in the cytosol; begins the degradation process by breaking down glucose into pyruvate

Question 8

Oxidative phosphorylation

Answer 8

electron transport and chemiosmosis for atp synthesis

Question 9

Citric Acid Cycle

Answer 9

a metabolic furnace that oxidized organic fuel derived from pyruvate

Question 10

ATP Synthase

Answer 10

the enzyme that makes atp from adp and inorganic phosphate

Question 11

Chemiosmosis

Answer 11

an energy coupling mechanisms that uses energy stored in the for of a proton gradient across a membrane to drive cellular work

Question 12

alcohol fermentation

Answer 12

fermentation where pyruvate is converted to ethanol by the release of carbon dioxide from the pyruvate then reduction of acetaldehyde to supply nadh

Question 13

lactic acid fermentation

Answer 13

fermentation of pyruvate directly to nadh

Question 14

obligate anaerobes

Answer 14

only carry out fermentation of anaerobic respiration

Question 15

facultative anaerobes

Answer 15

can make atp via fermentation when needed as well as respiration
