Active transport of sugars by the intestine of snail (Cryptomphalus hortensis Müller).
Sugar transport by sacs of everted intestine of snail have been measured in vitro at 30 degrees C. D-galactose, D-glucose and 3-O-methylglucose were actively transported against a concentration gradient from the mucosal to the serosal compartment. The transport of these sugars was inhibited by 5 times 10(-8) to 10(-6) M phlorizin. L-arabinose was also accumulated in the serosal compartment against a concentration gradient; in this case, transport was not affected by phlorizin. The snail intestine did not show any ability for D-fructose active transport but there was a clear uptake of this sugar by the tissue. The O2 uptake of the snail intestine was not significantly affected by the presence of either sugars or phlorizin.
