Glycolysis and anaerobic respiration

Question 1

glycolysis

Answer 1

the first stage of cellular respiration, which occurs in the cytoplasm and is common to both aerobic and anaerobic respiration

Question 2

pyruvate ions

Answer 2

the end product of glycolysis

Question 3

ethanol

Answer 3

an organic chemical with the formula C2H5OH produced as a result of anaerobic respiration (fermentation) in fungi and some plant cells

Question 4

lactate

Answer 4

ions of a 3-carbon compound (lactic acid) which is the end-product of anaerobic respiration in mammals

Question 5

anaerobic respiration

Answer 5

the form of cellular respiration that occurs in the cytoplasm when there is no oxygen present

Question 6

dehydrogenase

Answer 6

enzymes that remove hydrogen from a molecule (during oxidation reactions)

Question 7

redox indicators

Answer 7

chemicals which are different colours when they are oxidised and reduced; they can act as artificial hydrogen carriers to investigate respiration in yeast
