Question 4 Your Inner Mitochondrial Membranes o You remember the inner mitochondrial membrane, in which are embedded crucial 9 players in oxidative phosphorylation (see Fig. 9.15, p. 174, Reese et al.). You also remember that the inner membrane is thrown into a series of folds, called cristae, that increase the amount of inner membrane, and hence the number of copies of the aforementioned components of oxidative phosphorylation. Well, it turns out that the total area of inner membrane, summed over all the mitochondria in all the cells in your body, is about 14,000 m2. Express that area in terms of something(s) more familiar to us. E.g., what is the floor area of SI 240 in m2? What is the area of the hallway on the 2nd floor of SI building? What is the footprint of Main Classroom building ? What is the area of Euclid Avenue from E22nd to E24th? The playing field of Browns Stadium? Can you find some familiar "thing" that is comparable to the area of your own cristae? 2 9

Explanation / Answer

Answer

The total area of inner mitochondrial membrane is 14000

It's two times as much as floor space of white house (6500 meter square)

Total are of inner mitochondrial surface of all mitochondria in the body is 2 and half times that of surface area if a football ground(6000 meter square)
