 Energy Role of Starch

As starch is just a chain of glucose, $C_6{H}_{12}{0}_6$, molecules (and is broken down by the enzyme amylase found in our saliva) it can provide an organism with its main source of energy through aerobic or anaerobic respitation. This process uses glycose with (aerobic) or without oxygen (anaerobic) to create ATP, the energy "currency" of organisms.
