Holiday cookies rise (get bigger) when baked in the oven at 350oF because:
a. sodium aluminum phosphate (Na Al PO4) releases an acid that forms CO2 gas from sodium bicarbonate (Na+ HCO3-)
b. the Maillard reaction hydrolyzes wheat gluten in the batter
c. yeast ferment sugar (sucrose) in the batter to form CO2 at temperatures above 72oC
d. oxygen (O2) is needed to support the growth of lactic acid bacteria added to the batter
e. the amount of sucrose sugar added to Holiday cookies could make reindeer fly
