Abstract
1. The effect of various experimental conditions has been studied on the transfer of hexoses and fluid by everted sacs of rat small intestine.
2. The existence of glucose-dependent and glucose-independent mechanisms has been confirmed; the energy for the former comes from the citric acid cycle, and for the latter from either the glycolytic or pentose cycle.
3. The energy for glucose transfer against a concentration gradient can come from metabolism of glucose by some route other than the citric acid cycle, or it may come from the citric acid cycle.
4. Two-stage transfer of glucose is discussed as a possible explanation of the results.
