Keywords - respiration

Question 1

Aerobic respiration

Answer 1

Respiration that requires free oxygen to enable release of energy from glucose

Question 2

Anaerobic respiration

Answer 2

Respiration that releases energy from glucose or other foods without free oxygen

Question 3

Glycolysis

Answer 3

Initial stage in cellular respiration where glucose is broken down in cytoplasm to form 2 pyruvate mols.

Question 4

Link reaction

Answer 4

Process linking glycolysis + Krebs cycle -> hydrogen + CO2 removed from pyruvate to form acetylcoenzyme A in matrix of mitochondria

Question 5

Krebs cycle

Answer 5

Series of aerobic reactions in matrix of mitochondria by which energy is released through oxidation of acetylcoenzyme A

Question 6

Oxidative phosphorylation

Answer 6

Formation of ATP via electron transport chain (ATP synthase) in mitochondria during aerobic respiration

Question 7

Pyruvate

Answer 7

3 carbon compound produced from breakdown of glucose in glycolysis + used in link reaction

Question 8

Acetylcoenzyme A

Answer 8

2 carbon compound produced from breakdown of pyruvate in the link reaction + used in Krebs cycle

Question 9

Mitochondrial matrix

Answer 9

Gel-like liquid within inner membrane of mitochondria, where link reaction + Krebs cycle take place

Question 10

Cristae

Answer 10

Folds of inner mitochondrial membrane that are site of electron transport chain + oxidative phosphorylation
