The compartmentalization of the plasma membrane is essential for cells to perform specialized biochemical functions, in particular those responsible for intracellular and intercellular signaling pathways.

Question 4

The height function used in the chapter can be used to compute the change in area of a membrane when it suffers some deformation. Consider the height function

h (x, y)

defined over an

L \times L

square in the

x - y

plane. The function

h (x, y)

tells us the deformed state of the

L \times L

square. To compute the change in area, we divide the square into small

Δ x \times Δ y

squares and consider how each of them is deformed on the surface

h (x, y)

(see Figure 11.17 A). The function

h (x, y)

maps the small square into a tilted parallelogram.(a) Show that the two sides of the parallelogram are given by the vectors

Δ x (e_{x} + \frac{\partial h}{\partial x} e_{z}) and Δ y (e_{y} + \frac{\partial h}{\partial y} e_{z})

where

e_{x}, e_{y},

and

e_{z}

are unit vectors.(b) The magnitude of the vector product of two vectors is equal to the area subsumed by them, that is, a

x b = ab sin θ

where

θ

is the angle between vectors a andb. Using this fact, show that the area of the parallelogram is

d^{'} = 1 + (\frac{\partial h}{\partial x})^{2} + (\frac{\partial h}{\partial y})^{2} Δ x Δ y

(c) Now assume that the partial derivatives appearing in the above equation are small and expand the square-root function using

1 + x^{2} \approx 1 + \frac{1}{2} x^{2},

to demonstrate the useful formula for the area change,\[\Delta a=a^{\prime}-a=\frac{1}{2}\left[\left(\frac{\partial h}{\partial x}\right)^{2}+\left(\frac{\partial h}{\partial y}\right)^{2}\right] \Delta x \Delta y\]By integrating this expression over the entire domain, we can find the total area change associated with the surface. Divide both sides by

a = Δ x \times Δ y

to find a formula for the relative change of area

Δ a / a
