Explain The Breaking Down And Absorption Of Glucose Into The Bloodstream By Villi

In the following essay, I shall discuss the breaking down and absorption of glucose into the bloodstream by villi in the small intestine. In doing so, the three main pathways involved shall be explored, which include glycolysis, the Kreb’s cycle and chemiosmosis.

Once glucose is absorbed into the bloodstream by the villi, it circulates until it is absorbed by a cell in a process known as facilitated diffusion. This form of transportation, across a cell membrane, is useful, particularly in the absorption of glucose. Facultative transporters, in this case, glucose transporters cause the movement of glucose molecules from an area of high concentration, such as the surrounding blood supply, to a low concentration, which is, in this instance, the inside of the cell. Once absorbed by the cell, the first of the three processes mentioned above begins.

Cytoplasm, a gel like structure, causes all it’s components to be suspended, with which, include components such as dissolved nutrients, like absorbed amino acids, and waste products. It also has a large water content, ranging between 70-90 percent. Upon glucose entering the cell, this process commences.

Enzymes and products involved: During the breaking down of glucose by Glycolysis. Within this, it can be broken up into two steps, or phases. These are known as phase 1 and 2. Both involve the use of a multitude of
