The Dimensions of Mitochondria and Their Constituents
Assume that mitochondria are cylinders 1.5 µm in length and 0.6 µm in diameter.
a. What is the volume of a single mitochondrion
b. Oxaloacetate is an intermediate in the citric acid cycle, an important metabolic pathway localized in the mitochondria of eukaryotic cells. The concentration of oxaloacetate in mitochondria is about 0.03 µM. How many molecules of oxaloacetate are in a single mitochondrion
