During digestion, food is broken down into small molecules and is absorbed by the body, partly as glucose. Sugar enters the blood in the form of glucose.
Yes, organic molecules, such as carbohydrates, fats, and proteins, are a source of energy for the body. When broken down through processes like digestion and metabolism, these molecules release energy that is used for various bodily functions. Additionally, organic molecules also provide essential nutrients required for growth, repair, and maintenance of tissues and organs.
To absorb something in the blood the molecule has to be small and dis solvable. Glucose is very small and can be easily absorbed in the blood but starch molecules are very big. Really many glucose molecules put together form a starch molecule. Be cause starch is so big the enzymes have to cut it down so that it can be digested into the body. This is why starch molecules have to be broken down into glucose for digestion in animals.
The act of digestion consists of hundreds of separate decomposition reactions. Digestion occurs in the mouth as soon as you eat something. The enzyme amylase begins to decompose proteins by breaking the peptide bonds that hold them together. Complex carbohydrates are also broken down into simpler sugars which the body can burn for energy right away. These processes continue in the stomach and small intestines as well with different chemicals, like the enzymes pepsin and peptidase, which are specific to those organs. Generally speaking, proteins are broken down into amino acids, and polysaccharides, with their glycocemic bonds, are broken down into glucose. Unsaturated fats can be broken down as well, but saturated fats, with their long carbon chains, are very difficult to break down, which is why they are stored as fat.
so it can be broken down and transported to where it needs to be used in the bloodstream where it is diffused
Catabolism is the process in which a complex substance is broken down into its smaller components. For example is you excersice for a sufficient amount of time, your body will begin "burining fat" (i.e., breaking it down into smaller molecules to release the necessary energy required for continued exercise).
The process in which food containing large, insoluble molecules is broken down in to small, water soluble molecules (which can be absorbed by the body) is called digestion.
chemical digestion
Food is broke down into smaller molecules because if it isn't broken down, it'll get stuck in your body.
Digestion is the process through which food is broken down in one's digestive system. This is done by mechanical means and the release of enzymes in the alimentary canal. The food must be broken into smaller parts or substance so that the body can utilize them.
I suppose that you think to metabolism.
digestion
Digestion is a chemical reaction that takes place in the body, starting from the mouth and ending in the small intestine. It is a long process taking place in a 9m long alimentary canal. Ingestion in the mouth is when the food is taken in, digestion when the food is broken down into simpler molecules, absorption when the digested food is absorbed by the blood, assimilation when the digested food is utilised by the the body and finally, egestion where the unwanted food is excreted out from the body, through the anus. With these processes, there are many other organs in the body which help digestion to take place, some being the liver, pancreas, stomach, small intestine.
The sucrose molecules are broken down in the molecules of glucose which is the simplest form od the saccharides. The sucrose in the body is not readily metabolized but it has to be broken down into simpler form of molecules. The glucose is easily metabolized int he body.
Digestion is necessary because for energy from the food to be released and carried into the cells in our body the food must be broken down into soluble molecules for it to diffuse into the cells. Then energy is released during respiration.
Digestion
Digestion is the chemical and physical breakdown of food into compounds usable by the body. Absorbtion is the taking up of the compounds by the body. either through the stomach lining or through the intesitinal walls.
