Glucose and sodium move from the lumen of the small intestine into the blood via transport
proteins in the epithelial cells lining the small intestines (Figure 1), Based on Figure 1, describe
the direct source of energy used to move glucose into the epithelial cell from the intestinal
lumen, Explain how this system maximizes glucose absorption from the intestinal lumen into
the epithelial cells and from the epithelial cells into the blood,

Abeaker of water was heated and then placed on a bench in the laboratory. the water cooled until it was the same temperature as the air in the laboratory. which of these explains the mechanism by which the water cooled? a. heat energy was transferred from the water to the air. b. water molecules from the water formed warm water currents. c. the water molecules absorbed energy from the molecules in the air. d. the water released radiation until it contained no heat energy.
