hydrolysis reactions
The chemical reaction that is also called digestion is called hydrolysis. In this process, water is used to break down complex molecules into simpler ones that can be absorbed by the body for energy and nutrients.
The human body obtains reactants for cellular respiration through the digestion of food. Carbohydrates, fats, and proteins from the food we eat are broken down during digestion into glucose, fatty acids, and amino acids, which are then used as reactants in cellular respiration to produce energy in the form of ATP.
It is decomposition then combination reaction.
Digestion breaks down food into nutrients that can be absorbed by the body. These nutrients are then used in cellular respiration, a biochemical process that converts these nutrients into energy (ATP) that cells can use to carry out their functions. So, the nutrients obtained through digestion are essential for the cellular respiration process to occur and provide energy to the body.
Digestion and Respiration are alike in term of the fact that in both of them oxidation of food take place.
Cellular respiration.
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 is actually an endothermic process because energy is required to break down food into smaller molecules for absorption. This energy is used to drive the chemical reactions that break down the macromolecules in food into smaller molecules that can be absorbed by the body.
Digestion is the breakdown of absorbed substances, Respiration, on the other hand, is the breakdown of food molecules with a release of energy.
Respiration and 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.
