How Is Glucose Transported Around The Body

Blood is used to transport materials around the body. How is glucose carried by the blood?

Our science teacher didn’t tell us how to do this questions Oxegen is carried inside the red blood cells.

Glucose is absorbed directly into the bloodstream, mostly from the small intestine after you’ve eaten a meal. Your body can also make glucose from fats and proteins when it needs to. It travels in solution with blood plasma, meaning that it isn’t ‘carried’ by a protein the same way oxygen is by hemoglobin. However, to get across the plasma membrane of a cell, a glucose transporter is usually required; you can think of these as enzymes that are bound in the plasma membranes of individual cells that are designed to move glucose out of the blood and into the cell. Once in the cell, glucose may be modified (phosphorylated) by a hexokinase (a type of enzyme) that will prevent it from leaving again.
