What substances react in aerobic respiration and where do they come from?
Glucose and oxygen are the reactants. In humans glucose comes from digested food, and oxygen is breathed in from the air. In plants, glucose is made in photosynthesis, and oxygen diffuses in from the air.
Digesting food is an example of change of state?
Yes it is a change of state when the food is being digested. Solid food particles are changed into semisolid type of liquid in the stomach where it is further digested. Food molecules have to be changed into simple units before it can be absorbed into our cells.
why does oxygen affect food?
oxygen affects food by killing its cells it is something called oxydentation
What would happen to all life forms if there were no oxygen?
Life forms need oxygen in order to carry out the process of respiration. The oxygen breathed in is distributed around the body in the blood stream carrying food and nutrients to the cells. If there was no oxygen this procss could not take place. The life form would become more and more hypoxic and toxic leading to death.
Where does blood get get a new supply of food and oxygen?
blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
If the small intestine is shorter what will happen to the digested food?
Not all or less digested food will be absorbed by the body.
A substance from digested food that all your cells need?
oxygen
What do cells use to burn molecules of digested food?
oxygen
What happen to the food digested is it completely digested by the body?
not completely digested,and when digested the useful materials are absorbed mostly by the lining of small intestine.
What will happen if the small intestine is not in the digestive system in?
our food will not be fully digested and if our food will not be fully digested it will be hard to take out the waste that will go out from the anus
How do you call the process where digested food and oxygen are distributed to the body cells?
circulation
What would happen if not enough water is removed from digested food?
diarrhea
What will happen to the undigested food?
It still goes through the intestine and into the toilet just like digested food.
How do oxygen and particles of digested food get into the cells of your body?
Oxygen and particles of digested food get into the cells from the small intestine, from there they drain into the hepatic portal vein. The hepatic portal vein goes to the liver to filter out nutrients required and excesses are metabolized and converted.
What will happen if large intestine will not be able to reabsorb water from digested food?
you will develop diarrhea.
What would happen if you had no acids?
when we eat, food will not be digested, and then when it will go out, it would still have the same appearance.
What food molecules go into the blood?
The small molecules such as digested fat, carbohydrates and proteins.
