Question Description
Q.What did the researchers measure to compare the movement of oxygen molecules?Cell membranes are composed of phospholipids and serve as the boundary for cells. Phospholipids consist of a pair of fatty acids, which can have carbon-carbon double bonds or not, connected to a three-carbon glycerol with a phosphate group. The structure of phospholipids forms a bilayer with hydrophilic phosphate ends facing the outer and inner surfaces of the membrane, while the hydrophobic fatty acid chains extend into the space between these surfaces. This selectively permeable membrane facilitates the exchange of substances between the cells interior and its environment.Due to the hydrophilic and hydrophobic nature of the plasma cell membrane, only certain molecules can passively diffuse between the cells interior and the environment. The fluidity of the membrane affects passive transport, and the presence of other molecules, such as cholesterol, can significantly impact its fluidity. Temperature also influences membrane fluidity. Researchers conducted measurements to compare the speed of oxygen molecules (O2) moving through three types of membranes (lens lipid, POPC/CHOL, and POPC) with their movement through water. These measurements were conducted at different temperatures.a)Movement through different types of cellsb)Movement through different types of membranesc)Movement through water and aird)Movement through different cellular compartmentse)None of theseCorrect answer is option 'B'.
