Produce fats/oils for storage

What glucose converts to for cell wall strength

Cellulose

Combined with glucose to make amino acids

Aerobic respiration equation

C6H12O6+6O26CO2+6H2OC_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O

When anaerobic respiration occurs

When there is insufficient oxygen
