1) Placing phospholipids in water will spontaneously form a spherical structure called a: Group of answer choices lumen ball sphingoid cytoskeleton liposome 2) Saturated fatty acids Group of answer choices Have each carbon "saturated" with hydrogen Have each carbon "saturated" with other carbons Have each carbon "saturated" with hydrogen and are solids at room temperature Are solids at room temperature Contain double bonds 3)  In intestinal epithelia, glucose can be taken into cells against its concentration gradient. How can glucose be transported against its concentration gradient without the direct expenditure of ATP in intestinal epithelial cells? Group of answer choices It uses simple diffusion It uses the Glut1 transporter It uses the Glucose ATPase It uses the Glucose/Na+ symporter None of the above. Due to the Second Law of Thermodynamics, molecules cannot be moved against their concentration gradient.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
