Question 1

Aerobic respiration

Answer 1

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

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 an dyeast. A small amlunt of energy is transferred for the cells

Question 3

Endothermic reaction

Answer 3

Reaction that requires a transfer of energy from the environment

Question 4

Exothermic reaction

Answer 4

Reaction that transfers energy to the environment

Question 5

Glycogen

Answer 5

Carbonhydrate store in animals

Question 6

Lactic acid

Answer 6

End product of anaerobic respiration in animal cells

Question 7

Oxygen debt

Answer 7

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