Empty calories. The calories in alcohol have no nutritional value, but the body will burn them for fuel over calories obtained from food. The proverbial beer gut is not made of beer, but of fat. It forms when someone is ingesting large amounts of alcohol while eating a regular diet. The body burns the simple alcoholic calories because these calories cannot be changed to other forms such as fat and stored in the body. Food, however, can be changed to fat and stored for later use.
The problem is that, by taking in such large amounts of alcohol, with the body storing the food and nutrients as fat, the person is nutritionally deprived even though they may think they are eating well. The beer gut is not beer, it is food with all the vitamins and nutrients that food contains, stored as a large, fat belly.

carbon dioxide
The alcohol is "oxidized" like any other fuel, producing water and carbon dioxide. The reaction is C2H5OH + 3 O2 → 2 CO2 + 3 H2O + heat energy (from the CH bonds).
When alcohol is oxidized it becomes acetaldehyde, which is toxic. The acetaldehyde quickly become acetate, and then finally carbon dioxide and water.
Empty calories. That's how you can get fat.
The energy is transferred to ATP.
The sugar is not chemically changed / oxidized. Gently evaporate the water, and you get the sugar back.
fermentation
Water (H20) is split into 6O2, 24H+, and 24e-.
Complex hydrocarbons. These are broken down and oxidized by the cells of your body producing water and carbon dioxide, and releasing energy.
Glucose is oxidized into CO2. Oxygen is reduced into Water
Alcohol is not digested:- Alcohol is absorbed directly into the blood stream, about 30% through the stomach wall, and the rest from the small intestine. Human beings and their intestinal bacteria do not possess the necessary enzymes to break alcohol down. Alcohol therefore accumulates in the blood. Alcohol, once in the blood stream / body must be oxidized to get rid of it. Alcohol can only be oxidized in the liver, where enzymes are found to initiate the process. The first step in the metabolism of alcohol is the oxidation of ethanol to acetaldehyde which is catalyzed by alcohol/dehydrogenase containing the coenzyme NAD+. The acetaldehyde is then oxidized to acetic acid and finally to CO2 and water through the citric acid cycle. A number of the side effects from alcohol are directly linked to the production of an excess of both NADH and acetaldehyde.
Alcohol is changed to acetaldehyde in the liver, then finally is converted to acetic acid and water.
electrical energy in the heating elements is changed to heat and light. Only the heat is useful in heating the water.
