Food is broken down in a process called respiration. Enzymes are usually involved in the breakdown of food. Proteins are broken to amino-acids by protease, Carbohydrates broken down to simple sugars e.g fructose and glucose and Lipids (fats & oils) are broken down to fatty acids and glycerol by Lipase. Once they are broken down, they are taken to the cells where they're respired to produce Energy, Metabolic water and carbon-dioxide.
That would depend on the type of food. If the food is complex then it has to be digested and broken down into molecules that can be absorbed across the intestinal lining. This will take time and the process would be gradual (lasting hours).
However, if the food was pure glucose no digestion would be needed and the molecule would be available in the blood in a few minutes.
I do not really know I was just trying to look up the question if someone finds it please post it on this site.
It depends on the food. As soon as it is broken down, the food is used or stored in the form of calories. The term "calorie" only means the foods potential energy amounts.

If you vomit after eating are any of the calories extracted from the food?
I read somewhere that some calories will be absorbed. You have to eliminate the food before it hits the intestinal tract. I'm looking for the same answers. How fast do you need to eliminate the food before any calories are absorbed. Usually within 30 minutes. It's not a good idea to do this.
