hydrolysis reactions
Name the major fuel component of bio gas. What are it's other combustible compound?
Decomposition RXN, In decompositon RXN the compound present in the food that we eat are being simplified by our body for the elements to be properly distributed to the diffirent parts of the body for example, H2O (Water), When we drink water our body simplifies the compound through digestion, It seperates H (Hydrogen) which is used to clean our body and O (Oxygen) which is our means of life.
The food we eat contain starch,on digestion in mouth it is coverted into sugar.in body it gives co2,o2 with required energy.Hence digestion is an exothermic reaction.
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.
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.
When your body breaks down food into nutrients, chemical digestion is taking place. In contrast, physical digestion breaks down food mechanically into smaller particles.
Digestion-body absorbing food
by digestion of consumed food.
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.
