Question
Chapter 4.2, Problem 2CC
Summary Introduction
To calculate:
The ratio of an elongated cell that measures 125×1×1 arbitrary units. Predict how its surface to volume ratio would compare with reference to the Figure 4.6 “Geometric relationships”, in the textbook.
Introduction:
Surface to volume ratio is also called as surface area to volume ratio and it is denoted by SA:V. The ratio is the “amount of surface area per unit volume of object”.

The classic demonstration that cell plasma membranes are composed of bilayers depends on the following kinds of data: • The membrane lipids from 4.74 X 1o° erythrocytes will form a mono- layer of area 0.89 m² when spread on a water surface. • The surface of one erythrocyte is approximately 100 um in area. Show that these data can be accounted for only if the erythrocyte membrane is a bilayer.arrow_forwardCalculate the free energy changes at 20°C for the transmembrane movement of Na and K ions using the conditions presented Figure 9.1.
