Because glucose is a monosaccharide; it's a very small sugar molecule. "Mono" is Greek and means "one", so it only has one molecule group. Other sugars like for instance starch are called polysaccharides. "Poly" means "several". These can consist of hundreds of sugar groups, and therefore it takes much longer time to absorb it, because all the sugar groups need to be split into single groups. This is also why whole wheat bread makes you feel full and satisfied much longer than chocolate and loaf.

What nutrients affect blood glucose the most?
Carbohydrates have the most direct impact on blood glucose levels as they are broken down into glucose during digestion. Protein and fat can also have an indirect effect on blood glucose by influencing how quickly carbohydrates are digested and absorbed. Fiber content in food can help stabilize blood glucose levels by slowing down the absorption of glucose.
Why does your level of blood goes up when you eat glucose?
When you eat glucose, it is absorbed into the bloodstream, causing blood sugar levels to rise. The body releases insulin to help cells take in glucose for energy production and storage, leading to an increase in blood volume as glucose is transported throughout the body.
How does the glucose get to the body cells?
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.
Is the concentration of glucose higher in intestine or in the blood?
The concentration of glucose is typically higher in the blood compared to the intestine. After consuming food, glucose is absorbed from the intestine into the bloodstream to provide energy for the body. Any excess glucose is stored in the liver or muscles for later use.
What structure is most glucose absorbed into the blood?
Glucose is primarily absorbed into the blood through the intestinal epithelial cells lining the small intestine. This process occurs mainly in the jejunum, where glucose is transported across the cell membrane via specific transporters, such as SGLT1 (sodium-glucose co-transporter 1). Once inside the epithelial cells, glucose is then released into the bloodstream through facilitated diffusion via GLUT2 transporters.
Is it true that Glucose is absorbed back into the blood?
yes
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.
What nutrients affect blood glucose the most?
Carbohydrates have the most direct impact on blood glucose levels as they are broken down into glucose during digestion. Protein and fat can also have an indirect effect on blood glucose by influencing how quickly carbohydrates are digested and absorbed. Fiber content in food can help stabilize blood glucose levels by slowing down the absorption of glucose.
What term describes how quickly glucose is absorbed from food after ingestion?
glycemic index
Where does glucose and calcium enter the blood?
All nutrients we have taken are absorbed into the blood in the small intestine. The excess are stored in the liver from where if required is again absorbed into the blood.
What is the relationship between kcals and blood sugar?
Very indirect. kcals measures the amount of energy in food. And energy is transported through the blood in the form of glucose (sugar). But the amount of glucose in the blood is determined not just by how much food you eat, but by how quickly it's changed into glucose, how much of it is absorbed into the blood and how fast, and how quickly that glucose is accepted into the cells (which depends on insulin levels). So you can't really establish a direct relationship since there are too many other major factors.
What sugar enters the bloodstream quickly?
Glucose is the sugar that enters the bloodstream quickly. It is a simple sugar, or monosaccharide, that is readily absorbed by the body, causing a rapid increase in blood sugar levels. Foods high in simple carbohydrates, such as sugary snacks and beverages, can lead to quick spikes in blood glucose. In contrast, complex carbohydrates take longer to digest and result in a slower release of glucose into the bloodstream.
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
How quickly is fructose absorbed into the body?
I can't give you an exact answer but I know it is absorbed more slowly than glucose ( the fastest to be absorbed) and sucrose. Because of this, it is Ok for diabetics, in moderation.
How does glucose normally enter the blood?
Glucose is normally absorbed into the blood through the small intestine after we consume carbohydrates in our diet. The glucose molecules are broken down during digestion and then transported across the intestinal lining into the bloodstream. Once in the blood, glucose is carried to cells throughout the body to provide energy.
What sugar needs no digestion and can be absorbed directly into the blood?
Glucose is the sugar that needs no digestion and can be absorbed directly into the bloodstream. It is a simple sugar, or monosaccharide, that is readily available from various foods, particularly carbohydrates. Once consumed, glucose can quickly enter the bloodstream to provide immediate energy to cells. Other simple sugars, like fructose and galactose, also have the capability of being absorbed directly, but glucose is the primary energy source for the body.
What are substances not absorbed into the bloodstream from the digestive system?
amino acids glucose fatty acids n glycerol or absorbed in to the blood in the ileum
