B9 Respiration

aerobic respiration

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

anaerobic respiration

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

endothermic reaction

a reaction that requires a transfer of energy from the environment

exothermic reaction

a reaction that transfers energy to the environment

Glycogen

carbohydrate store in animals

lactic acid

the end product of anaerobic respiration in animal cells

oxygen debt

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