Assume an individual has no sodium in their intestinal tract. if this were the case the asorption of <u> </u><u> galactose </u> would be most affected.
<h3>Transport of d-galactose by the gastrointestinal tract :</h3>
Adult insects' gastrointestinal tract epithelium is where nutrients are absorbed because of the exoskeleton. The majority of physiological investigations have described the intestinal absorption of sugar as a diffusional mechanism, and no sugar transporter has been successfully cloned from an insect's digestive system to date. The current investigation makes a convincing case for the existence of a saturable galactose transport system in the gastric caeca of Locusta migratoria.
Galactose absorption is unaffected by changes in pH, the absence of K+, Cl, Mg2+, or Ca2+, either. However, facilitative transporter inhibitors like as phloretin, cytochalasin B, and theophylline reduce sugar uptake by about 50%. The presence of an mRNA coding for at least one equilibrative sugar transporter in the L. migratoria gastric caeca is further supported by the observation that Xenopus laevis oocytes microinjected with poly A+ RNA isolated from gastric caeca show sodium-independent galactose uptake that is three times higher than in non-injected oocytes.
