Glucose is absorbed through the small intestine into the capillaries. There are millions of villi (finger-like projections) that line the inside of the small intestine to increase its surface area for absorption. Villi have a very rich blood supply, so the glucose can be absorbed quickly and the blood is taken away quickly, maintaining a steep concentration gradient for more glucose, and other food, to be absorbed.

∙ 13y agoGlucose (C6H12O6) is converted to energy in cells in a metabolic process called CELLULAR RESPIRATION. Cellular respiration helps cells break sugar which helps in producing energy. It is an oxidation-reduction process or redox reaction.
C6H12O6 + 6O2 --> 6H2O + 6CO2 + 36 ATP (ENERGY)
The cellular respiration equation is a part of metabolic pathway that breaks down complex carbohydrates. It is an exergonic reaction where a high energy glucose molecules is broken down into carbon dioxide and water. It is also known as a catabolic reaction as a large molecule like carbohydrate is broken down to smaller molecules. This is just a small summary of the very complex reaction of cellular respiration that produces energy for the cell.
So basically, cellular respiration occurs in ALL cells - whether it be brain cells, heart cells, kidney cells, muscle cells, etc.
I hope this proves to be useful in answering your question on where glucose is converted into energy that can be used in the human body. However, if you are after the location of glucose production/metabolism/storage in humans = entirely different question :)

How does glucose normally enter the blood?
Like most nutrients, glucose sugar is absorbed into the blood stream through the walls of the small intestine from the food one eats.
Negative feedback with increase in blood glucose?
negative feedback can increase the concentration of glucose in the blood stream. if the blood glucose levels are too low, alpha cells will produce glucagon which causes the liver to break glycogen down into glucose. it is then released into the blood stream which increase the blood glucose levels.if it is too high, the beta cells will produce insulin which causes the liver and muscle cells to form glycogen from glucose. In addition, other cells are encouraged to use glucose in cell respiration rather than fats.both the beta and alpha cells are produced from the pancreas.
Why glucose is most preferred source of energy in cell?
In its form, glucose is ready for absorption into the blood stream. As such, it is the most preferred source of energy in body cells.
Where is fructose found in a living organism?
Lactose is a disaccharide made of the monosaccharides glucose and galactose. Lactose can serve as a transport or as an energy source when it is broken down. The monosaccharides are absorbed by the small intestine and stored in the muscles or liver.
How do your bodies deliver nutrients into the blood?
Your body delivers nutrients into the blood through the food that you eat. As food is broken down the nutrients are absorbed into the blood stream and are then carried to tissues and organs throughout the body.
What happens to glucose in the small intestine?
It gets absorbed into the blood stream via Lumen and a Glucose/Na+ symporter, Na+/K+ atpase and glucose 2 uniporter, but essentially is absorbed into the blood stream.
How does glucose normally enter the blood?
Like most nutrients, glucose sugar is absorbed into the blood stream through the walls of the small intestine from the food one eats.
Why all the carbohydrates are converted into glucose to give energy?
so that it will be simple and become easier to be absorbed int o blood stream.
What happens to glucose and amino acids when they are absorbed into the blood stream?
After the glucose is absorbed into the blood it is taken to the liver and is either stored or distributed to cells throughout the body for energy. To provide enough energy for the body the liver regulates blood glucose levels. Example: excess glucose is converted to glycogen in the liver and is stored. Likewise, if blood sugar levels fall it is reconverted back to glucose. Not sure about amino acids :P
What is glaxose-d?
Ita a monosaccharide or form of sugar also known as Dextrose or glucose-d. It is very rapidly absorbed into the blood stream as compared to table sugar which is a mixture of glucose-d and fructose.
Where in your body does the blood pick up glucose?
After we had the food, first nutrient that is separated out is glucose and this process is carried out at the intestine.If not food is take for long time (when fasting), the blood glucose level will drops and thus insulin secretion is also low on no. Then the liver start releasing glucose into the blood stream by converting stored glucogen to glucose.
Where does sugar enter the blood stream?
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.
Is it true that Glucose is absorbed back into the blood?
yes
How does crystal methamphetamine get absorbed by the body and get out of the human body?
absorbed through the blood stream
What does insulin pick up from the blood stream?
Glucose
How do nutrients like glucose get to your cells?
After glucose enters the large intestine, it along with other nutrients are absorbed into the bloodstream. From the blood stream it is carried by red blood cells to all parts of the body, where the glucose enters the interstitial space and is absorbed into the cells through a process called Cooperative transport. It usually uses Na ions for this purpose.
Where in the digestive system does the food get absorbed into the blood stream?
the liver
