Glucose is absorbed by Na+/glucose symporter into the intestinal epithelial cells.
<span>
Symporter is located on the apical membrane of the intestinal epithelial cell and it <span>is used for uptake of glucose from the intestinal lumen into the cell (against the concentration gradient). One glucose molecule and two Na+ enter the cell via symporter. Na+ concentration gradient and the membrane potential (generated from the Na+/K+ ATPase in the basolateral membrane) enable the function of the symporter. Glucose leaves the cell via facilitated diffusion on the basolateral membrane of the intestinal epithelial cell and goes into the blood.</span></span>
The Sun is the main cause for our weather, and different season (in different areas where you live it depends on how hot or cold it is also caused by the sun)
Most seasons, like in summer it's hot Also caused by the sun, in winter it snows because the sun is in a different location.
Epithelial membranes are made from epithelial tissue attached to a layer of connective tissue. There are three types of epithelial membranes: mucous, which contain glands; serous<span>, which secrete fluid; and </span>cutaneous<span> which </span>makes<span> up the skin. </span>
Answer:
1. transcription of Tau DNA in different directions.
4. different chemical modifications of Tau protein.
Explanation:
Tau gene transcribe in different direction which depends upon the animal age. This happens because at different age and developmental stage, animal produce different RNA binding proteins which leads to formation of alternative splice forms. This reaction is strengthen by the addition of phosphate and sugar molecules which again depending on developmental stage and time.
