PSIO 532 Study Guide - Final Guide: Inulin, Polysaccharide
Document Summary
Curve #1 (cid:862)(cid:454)(cid:863) = i(cid:374)uli(cid:374), a pol(cid:455)saccharide, (cid:373)olecular wt - 4,000 d. As [inulin] increases, filtered inulin increases excreted inulin = filtered inulin. Note that the formula takes the form y = mx - b + c where y = uxv, m. Thus, the slope of the curve for excretion of inulin = the gfr. Ux* v = (gfr * ax) - rx + sx. As aglucose t, filtered glucoset and rglucose t to a constant maximum. Glucose is filtered and reabsorbed, but not secreted. Also, as plasma [glucose] increases, reabsorption increases to a constant maximum value (determined by the. Tmfor glucose, concept of tm will be discussed later). excreted glucose < filtered glucose. At low plasma concentrations of glucose, all the filtered glucose is reabsorbed and none appears in the urine. After a certain point (threshold, to be discussed later), the slope of the curve for excretion of glucose also becomes parallel to than that for inulin (gfr).
