3) For each case given below, describe how the fluidity of membranes will change (increase or decrease) and why this change will happen. A. Increasing the number of double bonds (unsaturation) of the fatty acids in the phospholipids. B. Increasing the length of the fatty acid chains. C.

Transport mechanisms are often categorized according to the number of transported solutes and the direction of solute transport. 1. Uniporters transport one solute. 2. Symporters transport two different solutes simultaneously in the same direction. 3. Antiporters transport two different solutes simultaneously in opposite directions. After examining the examples of transport discussed in this chapter, determine the category to which each belongs
