Answer 1

important enzyme in the Krebs cycle, made from pyruvate oxidation

Question 2

aerobic

Answer 2

using oxygen

Question 3

alcoholic fermentation

Answer 3

produces 2 ethanol, 2 CO2 and 2 ATP

Question 4

anaerobic

Answer 4

not using oxygen

Question 5

anaerobic respiration

Answer 5

glucose catabolized in the absence of
oxygen

Question 6

ATP Synthase

Answer 6

enzyme that synthesis ATP

Question 7

cellular respiration

Answer 7

C 6 H12 O6 + 6O2 6CO2 + 6H2 O + 32 ATP

Question 8

chemiosmosis

Answer 8

protons flow back across the membrane through
a channel protein, ATP synthase, which couples the diffusion with
ATP synthesis

Question 9

fermentation

Answer 9

an anaerobic process that includes lactic acid or alcoholic fermentation

Question 10

gluconeogenesis

Answer 10

glucose formed from citric acid cycle and glycolysis intermediates

Question 11

glycolysis

Answer 11

the beginning of cellular respiration

Question 12

lactic acid fermentation

Answer 12

produces 2 lactate and 2 ATP

Question 13

oxidation

Answer 13

loss of electrons

Question 14

oxidation reduction reaction

Answer 14

electrons transferred between two
molecules

Question 15

oxidative phosphorylation

Answer 15

ATP is synthesized by reoxidation of
electron carriers in the presence of O2

Question 16

pyruvate

Answer 16

used in aerobic respiration, made from glycolysis

Question 17

reduction

Answer 17

gain of electrons

Question 18

respiratory chain

Answer 18

a series of protein complexes and other molecules that transfer electrons and protons across a membrane, drives ATP sythesis
