Respiration
Storage as starch
Produce fat/oil for storage
Produce cellulose for the cell wall
Produce amino acids for protein synthesis
What do plants need to make proteins?
Glucose
Nitrate ions absorbed from soil
Respiration - endo or exothermic
Exothermic
What does aerobic respiration use?
Oxygen

Movement
Keeping warm
Chemical reactions to build larger molecules
Balanced symbol equation for aerobic respiration
C6H12O6 + 6O2 ~> 6CO2 + 6H2O
What type of respiration releases the least amount of energy
Anaerobic
Word equation for anaerobic respiration in animals
Glucose ~> lactic acid
Word equation for anaerobic respiration in plants and yeast

What 3 changes occur to the heart and lungs when exercising?
HR increases
BR increases
Breath volume increases
What does the incomplete oxidation of glucose lead to?
Build of lactic acid
