Paper: An Analysis of the Mitochondria and the Eukaryotic Cell Diseases

These two membranes make two compartments to the organelle. First is the innermembrane space, which is located between the outer membrane and the inner membrane. It has a similar composition to that of the cytoplasm of the cell. The second is the matrix, which is inside the inner membrane. This contains enzymes that catalyze many of the steps in cellular respiration, which is another main process that provides the cell with energy. The chloroplasts are found in eukaryotic algae, leaves and other green parts of plants. Their measurements are about 2um by 5um. They have a double membrane surrounding it. They have flattened membranous sacs inside the chloroplasts called thylakoids, stacks of these thylakoids are called grana. This is where the chlorophyll is found. This is the site for the step in photosynthesis where light is initially converted into chemical energy. The stroma is the area remaining in the center of the chloroplasts. It contains a viscous fluid. Photosynthetic reactions that use chemical energy to convert carbon dioxide into sugar also occur here. Both the mitochondria and chloroplasts have their own genetic material and are capable of reproducing themselves. The mitochondria are passed on from the maternal parent only. The mitochondria are found in sperm, but in the tail not the head. The head is the only part that enters the egg, so the mitochondria are inherited from the mother. A metaphor for both the mitochondria and chloroplasts would be kidney bean. For the mitochondria | would also be sure to describe it as the powerhouse of the cell. It gives a good description of how important it is to the cells activity. Further information that | would like to share is the history of the mitochondria. Since this organelle has so much of its own organization and does most of its processes on its own, it is said that at one time the mitochondrion was its own cell. This is the Endosymbolic Theory....
