Name the major fuel component of bio gas. What are it's other combustible compound?
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.
It is decomposition then combination reaction.
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 of food release energy, so it's exothermic reaction
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 digestion of food in mouth and stomach and also in small intestine is not neutral , it is either acidic or basic.
The process that makes food available to your body is called digestion. During digestion, food is broken down into smaller molecules that can be absorbed by the body to provide nutrients and energy.
Nutrients and energy from the food are absorbed into your body.
Chemical reaction rate is increased by: -increased surface area -increased temperature -increased concentration of reactants -presence of a catalyst Chewing food essentially breaks up large chunks of food into smaller bits, increased total surface area for digestion.
It is a process in which the chemical composition of the food is changed. Reactions convert chemicals from the food to other substances. This process can take several stages and in the end you will have substances that the body can absorb and utilise.
When your body breaks down food into nutrients, chemical digestion is taking place. In contrast, physical digestion breaks down food mechanically into smaller particles.
