B9 Respiration

Question 1

aerobic respiration

Answer 1

an exothermic reaction in which glucose is broken down using oxygen to produce carbon dioxide and water and release energy for the cells

Question 2

anaerobic respiration

Answer 2

an exothermic reaction in which glucose is broken down in the absence of oxygen to produce lactic acid in animals and ethanol and carbon dioxide in plants and yeast. A small amount of energy is transferred for the cells

Question 3

endothermic reaction

Answer 3

a reaction that requires a transfer of energy from the environment

Question 4

exothermic reaction

Answer 4

a reaction that transfers energy to the environment

Question 5

glycogen

Answer 5

carbohydrate store in animals

Question 6

lactic acid

Answer 6

the end product of anaerobic respiration in animal cells

Question 7

oxygen debt

Answer 7

the extra oxygen that must be taken into the body after exercise has stopped to complete the aerobic
respiration of lactic acid
