In ethanol fermentation. One glucose molecule breaks down into two pyruvates (1). The energy from this exothermic reaction is used to bind inorganic phosphates to ADP and convert NAD+ to NADH. The two pyruvates are then broken down into two Acetaldehyde and give off two CO2 as a waste product (2). The two Acetaldehydes are then converted to two ethanol by using the H+ ions from NADH; converting NADH back into NAD+ (3).
