the breakdown of a two-carbon compound produced by the Calvin Cycle

Question 8

Producer

Answer 8

something that makes its own food

Question 9

when hydrogen is gained

Question 11

Aerobe

Answer 11

a cell that respires using oxygen and executes it in four steps; Glycolysis, Link Reaction, Citric Acid Cycle, and Oxidative Phosphorylation

Question 12

Anaerobe

Answer 12

a cell that respires without oxygen and executes it in two steps; Glycolysis and Fermentation

Question 13

Strict Anaerobe

Answer 13

an organism that cannot survive in an atmosphere of oxygen

Question 14

Facultative Anaerobe

Answer 14

a microorganism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent

Question 15

Phosphorylation

Answer 15

the transfer of a phosphate group

Question 16

Photophosphorylation

Answer 16

the productions of ATP by chemiosmosis during the light reactions of photosynthesis

Question 17

Substrate Level Phosphorylation

Answer 17

the formation of ATP occurring when an enzyme transfers a phosphate group from an organic molecule to ADP

Question 18

Oxidative Phosphorylation

Answer 18

the production of ATP using energy derived from the redox reactions of an electron transport chain.
